Frustrating that Storm sorcerer isn’t an option

 Totally agree.

WotC, please give the older Sorcerer subclasses their own bonus spell lists!

You've given us a taste with Aberrant Mind and Clockwork Soul, and now we know it's too good to give up.

 Yeah it would be cool if shadow sorcerers had access to some warlock spells or spells that have to do with the Shadowfell, like Ray of Enfeeblement, Vampiric Touch, Illusory Dragon, maybe even Eldritch Blast, storm sorcerers had access to more spells that actually have them calling upon natural disasters like Ice Storm, Call Lightning, and Control Water, and draconic sorcerers had more elemental spells that correspond to their draconic ancestor similar to circle of the land druids but with their ancestry instead of the environment.

But seriously, Shadow Sorcerer needs more spells that have to with the shadow fell. I don't see the point in saying they have a connection to the Shadowfell if their spells don't reflect this very well. And that goes for most of Sorcerer's subclasses. Clockwork Soul and Divine Soul's expanded spell list were huge steps in the right direction. I just want my sorcerous origin to feel like it effects more of my magical abilities.

Where is it said that it isn't, though?

Frustrating that Storm sorcerer isn’t an option

WotC, please give the older Sorcerer subclasses their own bonus spell lists!

You've given us a taste with Aberrant Mind and Clockwork Soul, and now we know it's too good to give up.

Psionic Soul offers a lot of versatility to a class that previously has been all about squeezing the most out of its narrow options.  It softens some of the sorcerer's hard, once-per-level tradeoffs into a more frequent series of calculated risks.

I see some commenters pointing out that the probability of totally burning out your Psionic Talent die (or PT die) is low, but the main risk is that, over the course of the day, your die shrinks, making your character less effective.  You can reset the PT die to the starting value only once per long rest, and when the starting size of the PT die is a d8 or higher, players may decide not to wait until they're down to a d4.

Psychic Sorcery essentially offers an upgraded Subtle Spell at 1st level.  It automatically eliminates all component requirements for cantrips and 1st-level spells and it has a high probability of eliminating those requirements for low-level spells.  This feature is distinctive and strong right out of the gate and is not limited to sorcerer spells, so a one-level multiclass dip could give several other classes a lasting boost.
Since they get a solid replacement for Subtle Spell (at least for low-to-mid-level spells), Psionic Soul sorcerers have more flexibility to explore the other metamagics starting at 3rd level.  Crucially, you can combine this feature with metamagics like Heightened Spell, Quickened Spell, or Twinned Spell, which could create some powerful combos—albeit at a cost of two of your resources.

Of course, if you don't roll high enough for the spell level, you could fail.  But the possibility of not needing material components can be handy in many situations. 

• Sometimes you just want to avoid expenditures on costly and hard-to-get components.  No need for a 1st-level sorcerer to get a 50gp diamond to cast Chromatic Orb if you're willing to risk the PT die each time.  No need to get 250gp metal forks tuned to each plane for Plane Shift... just roll a 7 or higher on your PT die and you can go to any plane you want.
  
  
• Since half of sorcerer spells have material components, Psionic Soul sorcerers can potentially cast a much wider range of spells when they simply can't use material components.  On some occasions your material components are taken from you, like when you're captured by enemies or attending a VIP event with strict security.
  
  
• This is also a lovely way to avoid suspicion when casting spells. 
  • Jeremy Crawford says Counterspell works against spells that are cast with only material—no verbal or somatic—components.  (I don't know why: the sorcerer could just handle the material with his hands stuffed in his pockets, right?) The same principle should apply to Temporal Shunt.  So if you don't even need material components, that means a lot more of your spells can't be countered.
    
    
  • Casting silently and motionlessly means that if you are hidden and you cast a spell that doesn't give away your position, it's quite possible to remain hidden without needing to actively hide again.
    
    
  • You can cast spells while keeping your hands visible and motionless, making you even better at inconspicuous casting than the average sorcerer with Subtle Spell.  You could look like just another guy on the street, passing by, while you cast any spell that doesn't obviously originate with you.  If you're creative, you can make an attack look like an accident, or make someone else seem to be the source of the attack.  You could even make it look like you're trying to help the victim.
• If you don't need a free hand for somatic and material components, you can use both hands for other things.
  • There are obvious situational uses, like casting those spells while both hands are grasping a ledge, holding the reins of a galloping horse, or handling a heavy object.
    
    
  • This also opens up fighting style options for multiclass characters, since (again) it doesn't apply only to sorcerer spells.
    • Consider the following rules for spellcasting without Psychic Sorcery:
        (a.) If a spell has material components with a price (e.g. a 50gp diamond) or that are consumed (like the holy water or powdered silver and iron in Protection from Evil and Good), then the character must have a free hand to grab that component to cast the spell.  You cannot use a spellcasting focus instead. 
        (b.) If a spell has a somatic component and unpriced material components that are not consumed, then you can perform the somatic component with the hand that holds the material components—or a spellcasting focus, if your class or subclass can use a focus.
        (c.) If a spell has a somatic component but not a material component, then the hand performing somatic components cannot be holding a spellcasting focus (or anything else).
      As a result: 
        (d.) If you're just swinging a two-handed weapon, you can hold the weapon in one hand so you have a free hand.  But if you're carrying a weapon and a shield, or two weapons, then your spellcasting options are limited unless you drop (or stow) an item.
        (e.) Starting and maintaining a grapple requires a free hand, so if you're holding an item in the other hand, your spellcasting options are limited until you drop/stow the item or end the grapple.
      
      There are several ways around these limitations, all of them incomplete:
      
      • The War Caster feat allows you to cast spells with somatic components even while holding two weapons or a weapon and shield, but it doesn't replace any material components.  And your character may need to go a long time without that feat.
        
        
      • Paladins and Clerics can use a shield that bears their holy symbol/emblem as a spellcasting focus.  College-of-Swords Bards and Profane Soul Blood Hunters can use a weapon as a spellcasting focus.  Druids, Wizards, Warlocks, and Sorcerers have only one option that functions as both a weapon and a focus: a staff—a wooden staff for a Druid—which can be used as a quarterstaff (DMG page 140).  (But remember, if the spell has somatic components but no material components, these characters will have to use a free hand to cast it.)
        
        But many characters cannot do even this.  Paladins (or Clerics) who wield a second weapon instead of a shield, or grapple, are limiting their spellcasting options.  Sorcerers have also been known to multiclass with Hexblade Warlocks and Valor Bards, subclasses that are proficient with martial weapons and shields.  There haven't been a lot of sorcerer multiclasses with College-of-Whispers Bards, Eldritch Knights, Arcane Tricksters, Rangers, Bladesingers, or Circle-of-Spores Druids, but considering what one level of this subclass can do, maybe that could change.  In many cases, people believe dual-wielding and/or sword-and-board are non-viable (or very suboptimal) options for those classes/subclasses, but this could change that calculation.
        
        
      • A Ruby of the War Mage can be affixed to a weapon to allow it to be used as a spellcasting focus.  Obviously, your DM may not make this item available to just anyone who wants one, but it's listed as a common item in XGE.  It does require attunement, though.
        
        
      • During their turn, as part of their action or movement, characters can interact with one object for free as long as it doesn't require special care or present an unusual obstacle (PHB page 190).  But if you wanted to interact with a second object or interact with the same object twice, that would require an action.  So you could, say, sheathe your weapon and cast a spell, but then you couldn't draw the weapon again until your next turn.
        • The rules specify that you can do this on your turn.  So it doesn't work when you're trying to cast a spell on someone else's turn, as with reactions.
        • You cannot stow or re-equip a shield with this free interaction.  It takes an action to doff a shield, and another action to don it again to gain its AC bonus.
        • If you have the Dual Wielder feat, sheathing one of your two weapons lowers your AC by 1. 
      • Technically, the rules (as written or intended) allow characters to instantly drop a held item—not including shields—on the floor (which doesn't count as interacting with the object), cast a spell that requires a free hand, then (on their turn) pick up the item again.  But this comes with some risks, especially if your DM rankles at you doing this habitually:
        • If you tried this while flying, swimming, climbing, or walking in a precarious place like on a rope bridge, you might drop your item out of reach.
          
          
        • If you dropped the item in a heavily obscured place—like tall grass or muddy water, a Fog Cloud, or mere darkness—you might have a harder time finding and picking up the item.  That might take your action, and/or it might require an Investigation or Perception check.
          
          
        • Whenever you drop an item, you are no longer holding/carrying it, which gives enemies an easy opportunity to steal the item, knock it away, or damage it.  Here are several methods by which your enemy might do that, many of which require using the Ready action and waiting until the moment you drop it:
          • Pick up the item with his hands, Mage Hand, Telekinesis, or the Psi Knight's Telekinetic Movement. 
          • Task an Unseen Servant or his familiar to fetch any dropped items. 
          • If the object isn't magical (like a common shortsword), release Animate Objects and turn the dropped object against you or order it to fly away. 
          • Bury the item (and maybe you) with Mold Earth or Transmute Rock.  Good luck digging it out.
          • Push the item away from you with Gust or Catapult (perhaps over a ledge or into a body of water), or potentially separate you from the item with Thunderwave or Reverse Gravity (if you make your save, the item still doesn't).  Or do either of these things with Levitate.
          • Trap you in a Whirlwind so that any object you drop is sucked in for the duration of the spell.
          • Blind you or heavily obscure the object, so you can't see the object to pick it up easily.  
          • Damage you and your item separately with Shatter, Lightning Bolt, Fireball, Chain Lightning, Fire Storm, etc.
        • In order to cast reactions like Shield, Absorb Elements, Hellish Rebuke, Feather Fall, and Counterspell, you could drop an item, but then you wouldn't be able to pick up the item until your turn. (If you cast Feather Fall on yourself, remember that the item falls much faster and harder than you do.)  That gives enemies time to mess with the item even without using the Ready action.
          
          
        • If you have the Dual Wielder feat, dropping one of your two weapons lowers your AC by 1 until you hold a second weapon again.
    • So in summary, many spellcasters who wanted to fight with two weapons, or a weapon and a shield, or grapple while still holding an item, could take one level as a Psionic Soul sorcerer and be able to seamlessly cast spells while fighting.

Psionic Discovery (gain a Divination or Enchantment spell you expect to be useful in the next few hours) makes sorcerers much more adaptable, and more likely to use spells that have relatively narrow applications.  Look at the list of the sorcerer's Enchantment and Divination spells.  If you know you can learn mainstays like Suggestion and Hold Person every time you're about to venture out, and learn narrower spells like See Invisibility when you think it's particularly likely to come up, that enables you to load up more of your limited base of spells known with non-Enchantment, non-Divination spells.  But you still may want to have, say, Detect Magic available all the time.

• As long as you roll okay, you can keep adding a spell known every 10 minutes.  So at 1st level, on your first day of adventuring, you could potentially choose between 6 different 1st-level spells!  But (a.) rolling a die several times could grind the game table to a halt in a not-fun way if you're not careful, (b.) meditating for several 10-minute chunks at inopportune times would slow down your party, and (c.) rolling your PT die that much reduces the number of times you can speak telepathically and cast stealthy spells before your PT die is statistically likely to run dry.
  As you gain levels, find ways to make these Psionic Talent die rolls unobtrusively, or everyone at the table is going to lose patience with you as you try to add a pile of spells to your repertoire and burn hours out of every adventuring day.  You don't want to be that player saying, "Okay guys, before we delve into the ruins, I just need to meditate for 80 minutes so we're ready for anything; stand by while I make eight rolls."  The designers of 5th Edition took pains to prevent the game from being bogged down that way, and a good DM will find ways of encouraging you to be efficient with your time and rolls, like rolling for a combat encounter whenever you sit still for too long.  Here are some ways to reduce that burden:
  
  
  1. Since you can spend two hours of a long rest on light activity like the meditation described in this feature, you can spend up to 120 minutes toward the end of a long rest to learn spells that will carry you through the early hours of the day.  That's enough time to learn up to 12 Divination and Enchantment spells, and you won't be burning your party's adventuring hours.  At the end of your long rest, your PT die returns to its starting size, so don't worry about running dry unless you think your long rest could be interrupted in the final stretch.
     • You get even more time if you're an elf.  Even their version of "sleep" is described as four hours of meditation.
     • This still means you're rolling a series of PT dice, so be efficient and unobtrusive!  Keep a list of your top-priority Divination/Enchantment spells, and be prepared to record how many hours you get for each spell when you roll the die.
     • During your adventuring day, remember that your ability to pick up spells for the next morning depends on what you'll be able to roll during your long rest.  If you burn out today, you could wind up burning the candle at both ends tomorrow.
  2. Probably the easiest way to avoid delaying your party and the game table is to make more of these rolls during short rests, when the players are busy rolling Hit Dice anyway.  When your party needs a short rest, you will have learned something about which Divination and Enchantment spells are most likely to be useful in this environment. 
     • For example, you might only add Hold Person if the dungeon seems to have humanoids, or add Comprehend Languages if this place is crawling with enemies who are using an unfamiliar language to coordinate against you, or skip the charms if all the monsters here are immune (like undead who are immune to Sleep).
     • If you don't really need to roll Hit Dice, you could even cut down on delays by casting Catnap (an Enchantment spell) to give other members of your party a 10-minute short rest, and during those ten minutes you meditate and add one spell that you expect will be useful in this area.
  3. One way to avoid delaying your party in an annoying way, and take fewer potentially unnecessary risks with your PT die, is to just wait until you're confident you'll need a spell.  For example, if your party comes across a text that none of you can read, and you're not under a lot of time pressure, you can take ten minutes to meditate and learn Comprehend Languages.  People are more forgiving of you rolling dice if you're trying to accomplish a specific task.  (Especially if you give them that Catnap at the same time.)
     Of course, your DM could present you with a challenge in which you need to understand a language immediately or miss an opportunity.  So you're taking a calculated risk that depends on how often you get advance clues from your DM about what you're going to need in the coming hours.
• If you're worried that you don't get the innate AC bonus granted to some other sorcerer subclasses, you can think of this feature as freeing up some space for Mage Armor in your spells known.  Sure, it's not as dependable as having an innate AC bonus, and you'll have to use a spell slot, but you get ample compensation for it that grows with time; pretty soon you'll have extra space for Shield too.
  
  
• Compared to other UA subclasses that have offered ten specific spells to grant over the first nine class levels, Psionic Discovery is a much more elegant solution to the common grouching about sorcerers' limited number of spells known.  Within some broad thematic boundaries, the player gets to make choices about managing resources to access those spells.  Also, this "expanded spell list" continues right up to 9th-level spells, so the subclass continues to shape a distinctive character concept throughout the late game.
  • Psionic Soul sorcerers might just cast 9th-level spells other than Wish from time to time!
• The fact that this feature can be used during a short rest is only going to add to the theorycrafting of the Sorcerer-Warlock multiclass, with its (in)famous short rests.  "I can recharge sorcery points/spell slots and add to my spell list at the same time!"
  
  • Speaking of short rest interactions, it might be worth considering a level of Psionic Soul with your Circle-of-the-Land Druid.  The Circle of Dreams 6th-level feature might also be convenient.

Telepathic Speech can be potent in all three pillars of the game: social, exploration, and combat.  It really helps with coordinating while you're sneaking around or being observed closely.  It's also a cool feature to have when you're a Charisma-based character who's likely to be a "face" of the party: you can talk to people, perhaps attempting persuasion or intimidation, without anyone else knowing you're having a separate conversation.  Since you can form the bond with anyone you can see and potentially wait hours (when you're miles apart) before you even start talking to them, you could talk to someone even though you were only one face in the crowd that day.

• You could form a Telepathic Speech bond with a character (bonus action), use Psychic Sorcery to stealthily cast Suggestion (a 2nd-level Enchantment spell, 1 action to cast), telepathically tell that character what to do, and nobody would know you had done it.  You could even use Heightened Spell to impose disadvantage on the saving throw.  It would be costly—two rolls of the PT die, plus sorcery points if you use metamagic—but in many situations you've just dramatically changed the encounter.
  
  
• From the wording of the spell, I think casting Tongues (a Divination spell) would allow you to make those Telepathic Speech chats across language barriers for one hour.  It would cost you a 3rd-level spell slot, though.
  • I don't know how often this would be useful, but you could also use the 1st-level ritual Comprehend Languages to understand what others said to you telepathically, but they still wouldn't necessarily understand what you said back to them.
• I appreciate that this feature doesn't overly duplicate the kalashtar's Mind Link, which is always ready without a resource cost, making it much easier to talk telepathically to multiple people in a short time, even across language barriers.  Nor does it overly duplicate the ghostwise halfling's Silent Speech or the Great-Old-One Warlock's Awakened Mind.  Psionic Soul sorcerers need to be more selective with their telepathy.

Psychic Strike, pleasantly, is not just a re-skin of the Draconic sorcerer's Elemental Affinity.  On the plus side, it gives you total flexibility on damage type, so you can boost a much wider variety of spells and don't run into problems when you encounter an enemy that has resistance or immunity to the one damage type the Draconic sorcerer selected at 1st level.  Indeed, you can do two different kinds of damage with one spell, which gets around some resistances.  And since Psychic Strike involves adding a damage die, it can be doubled on a critical hit.

But there are limitations that make this feature less suited for mass destruction.  For starters, it can only add damage to one creature, so you can't increase the damage dealt to every creature in a Fireball blast radius, for example.  It also doesn't add damage to cantrips.  It only works on sorcerer spells, which rules out multiclass combos like Dissonant Whispers or Guiding Bolt.  It can only be applied once per turn, so you can't increase damage from a spell that you're concentrating on and a new spell cast this turn.  It doesn't allow you to spend a resource to gain resistance to psychic damage, which would have duplicated another kalashtar trait.  And of course, you have to roll the PT die each time, which is a risk.

The kind of spells that might get a stronger critical hit from Psychic Strike—non-cantrip sorcerer spells with an attack roll—only fill a short list of spells:

• 1st-level: a handful of spells like Chromatic Orb and Chaos Bolt
• 2nd-level: Scorching Ray
• 4th-level: the lightning bolts of a Storm Sphere (pretty good for beating up bosses)
• 5th-level: the beams of radiance from a Wall of Light.  I sadly doubt that Animate Objects counts as "deal[ing] damage to a creature with a sorcerer spell" since it's the creatures you create who deal the damage, not the spell itself.
• 7th-level: Crown of Stars.

Maybe this feature will make those spells more popular, but I suspect most sorcerers, most of the time, will end up using this on spells that don't have attack rolls.

On the other hand, if you use this subclass, there's a lot less pressure to take Subtle Spell early and spend sorcery points on it, so it's easier to make up some of the difference with the Empowered Spell metamagic, which can boost area-of-effect damage at a low cost.  One more elegant tradeoff for this subclass.

Mind Over Body may have a sorcery point cost, and you may not fly for quite as many hours as a Draconic sorcerer, but the flexibility you gain makes up for it.  And you can get multiple effects for one roll of that PT die.  This is another case, like Elemental Affinity/Psychic Strike, where the Draconic sorcerer does a single important thing very well, but the Psionic Soul takes risks with resources to be more versatile.

Psychic Aura could help keep you safe—note the lack of a saving throw, so it hobbles any target that isn't immune to psychic damage—but you'll have to be creative to turn the tide of battle with it.  It's nice that it doesn't cost sorcery points, so you can use those points on Mind Over Body (or Quickened Spell to dash/disengage/dodge) to get in and out of range of enemies.

Final thoughts:

• These combined features will cause Psionic Soul sorcerers to play noticeably differently than other sorcerers.  DMs will have to throw a different set of challenges at a party that has this character in it.
  
  
• Playing this subclass requires rolling a lot more dice and keeping track of extra resources (on top of sorcery points and spell slots): not only PT die, but also time: these sorcerers will keep asking their DMs how many hours have passed since they did this and that, and how many hours they expect to travel before they get somewhere.  DMs and players will have to adapt to keep the game flowing.
  • A DM could turn a possible annoyance into a story hook by making time pressure into a bigger source of dramatic tension.  Force the player to make more choices about time: "Do we take the dangerous shortcut, or do we risk that when I arrive I won't be able to cast this spell or that one?"  If the character is in a town that rings bells on every hour, the DM can indicate how much time is passing, causing the player to worry about how much time is being spent on this or that task.  Alternately, the DM can privately keep track of time and exploit the player's uncertainty about how much longer they'll be able to cast a spell, in which case it would be very useful to have a character with the Keen Mind feat around to keep track of time.
  • It's very plausible to roleplay this character as anachronistically obsessed with time.
• The combination of those first-level abilities makes the sorcerer, for the first time, an attractive candidate for a one-level multiclass dip.  It used to take a much bigger dip of three sorcerer levels to reach the really interesting interactions, but now you can significantly change your style of play with a one-level detour: casting low-level (and sometimes mid-level) spells without any components, telepathic communication for being sneaky, and a bunch of extra low-level spells for versatility.
  • Paladins, Warlocks, and Rangers only ever cast up to 5th-level spells, so a d6 for Psychic Sorcery could potentially allow them to daily cast a decent number of spells without using components throughout their level progression.  Eldritch Knights and Arcane Tricksters only ever cast up to 4th-level spells, so even dropping to a d4 won't necessarily stop them from casting a top spell without components.  Of course, if they reach higher spell levels it gets harder to roll high enough to cast those without somatic and material components—if they're in a rush.
    
    
  • Subtle Spell is the best thing about being a sorcerer.  It's not bluntly powerful in the sense of making you do massive damage or making you unkillable, but it enables you to do many fun, creative things no other class can do.  So while it should be interesting to see how multiclass characters make use of a similar power with a one-level dip, I hope it doesn't make the sorcerer less distinctive, but instead makes those players want to try playing a full sorcerer.  (After all, a second level gets you Font of Magic for a little more flexibility.  And 3rd level gets you metamagic and 2nd-level spells and twice as many spell slots...)
• The flavor of all these features comes together so well, forming such a distinctive character concept, that roleplaying comes naturally.
  • With Psionic Discovery and the changing of the PT die, there's a smooth progression of distinctive traits of this subclass throughout your level progression.  In that way, it's similar to a Divine Soul.  When other sorcerer subclasses get a new feature at 14th level, that is the first time since 9th level or even 6th level that they've picked up a new distinctive trait that separates them from other sorcerers.
    
    
  • It's easy to imagine roleplaying several of the multiclass ideas I've presented, too.
    • It would be perfectly appropriate for a College-of-Whispers Bard, with their psychic blades and mind-reading powers, to also have a touch of sneaky Psionic Soul sorcerer.
    • An Arcane Trickster would be far more tricksy if she could cast spells without components and speak telepathically, and would be able to pull off a greater variety of mischief with a broader magical toolkit.  Comparing this multiclass to the Soulknife is a fun exercise.
    • Likewise, a Trickery Cleric could create even more chaos if she could speak remotely and cast spells without showing any signs of doing so.  Perhaps her experience with subtle sorcery instilled a taste for subterfuge and pranks, with her "imaginary friend" egging her on.
    • Eldritch Knights with a Psionic Soul would be terrifying: mage-warriors casting spells without uttering a word or waving their arms, so they can use both hands for physical combat.  Whispering directly into the minds of their enemies and allies alike.  Accomplishing tasks with more subtlety than other Eldritch Knights, their focus on Abjuration and Evocation balanced on a broader foundation that can flex toward Enchantment and Divination.
    • A Psionic Soul Bladesinger might be a high elf whose psychic talents and intellectual interests tend toward the gracefully arcane, compared to the relatively brutish Psi Knights.
    • Those who spend time in the wilderness know the value of being able to stalk prey silently and with minimal motion.  Someone with the Psionic Soul's stealth could make an exceptional ranger or druid.
      • The Gloom Stalker and the Circle of Dreams are probably the best thematic fits for a Psionic Soul, but others could work too.  It might be easier to imagine the Circle-of-Dreams Druid having their psionic potential awakened by drinking from a glittering stream touched by the Feywild, whereas a Circle-of-Spores Druid naturally might have survived an encounter with mind flayers in the Underdark.
    • Honestly, a Hexblade Warlock isn't as natural a thematic fit as a Great-Old-One Warlock, but it's not hard to imagine an origin story. 
      • Maybe the "old wound" from the "near-fatal injury" was dealt by a hexblade, but as the one who wielded the hexblade fell, the blade forged a new pact with you.
      • Or perhaps the "spirit [who] haunts your mind" is connected to the Shadowfell, like an ancient shadow dragon (perhaps a shadow version of a sapphire dragon or brainstealer dragon), or a khayal (shadow genie) noble, or someone even more powerful.  This entity arranged for your pact with a hexblade, or the hexblade was drawn to you because of your connection to this entity.
• By contrast with the Aberrant Mind origin, the Psionic Soul origin is much better about not duplicating (or heavily overlapping) core features of the kalashtar race.  It would make sense to have a kalashtar Psionic Soul sorcerer without heavy homebrewing, and it would be thematically appropriate.  (Even though the new kalashtar traits aren't quite as tuned for a sorcerer as the old ones.)

Overall, this is a lovely subclass.  It isn't about overwhelming power; others can shell out more damage or survive deadlier onslaughts.  It's about how this subclass keeps the player engaged throughout the game, managing resources (PT die, time, sorcery points, spell slots, spells known) through all three pillars of play, making tough choices.  And when they take those swings, they can do fun, creative things no other character can do.

For the Psionic Soul, the text should be clearer about what happens when you try to cast a spell with Psychic Sorcery but you don't roll the level of the spell or higher.  For example, say I tried to cast Gate without a 5000gp diamond, but I failed to roll at least a 9 on my Psionic Talent die to preclude the material requirement, or I tried to cast Counterspell while keeping my hands still but I failed to roll at least a 3 on my Psionic Talent die.

• The description says, "When you cast a spell, you can use your mind to form it, rather than relying on words, gestures, and materials. To do so, roll your Psionic Talent die. The spell then requires no verbal component, and if you rolled the level of the spell or higher, the spell doesn’t require somatic or material components either."  But whether you're able to cast the spell depends on whether you provide the components first.  The spellcasting rules in the PHB state, "A spell’s components are the physical requirements you must meet in order to cast it. [...] If you can’t provide one or more of a spell’s components, you are unable to cast the spell."  If you can't (or don't) provide all the components, does the initial desire to cast the spell use your action/bonus action/reaction anyway?  Does it burn a spell slot?  Does it consume any sorcery points you wanted to spend on metamagic for that spell?  (Aside from Empowered Spell, which you trigger when you roll spell damage, the trigger for all metamagics is, "When you cast a spell...")
  
  
• If you fail to roll high enough to preclude the use of somatic components, can you then decide whether or not to cast the spell with somatic components, or must you go through with the casting?
  
  
• The rules say, "You lose concentration on a spell if you cast another spell that requires concentration."  (Jeremy Crawford has clarified, "your concentration on it ends the moment you start casting another concentration spell.")  If you're unable to cast the new spell because you failed to provide a component (or unwilling to cast it if you must use a component), do you lose concentration on the old spell?

One problem with the psionic soul is that once you run dry on your Psionic talent dice, your whole subclass is out the window. And if you take a feat like telekinetic, where you are using your dice every turn as a bonus action, it could run try decent-ally fast at lower levels.

Is anyone else just getting Draconic Bloodline as their only sorcerous origin option, or is it just me? Because if it is, then GODDAMN IT!!

Anyone else wishes all the Sorcerer's subclasses got extended spell lists?

[tbh, I think 10 is too many for some of these, sorcs end up having more spells than the bard by 20th level (25 total for sorcs, 22 for bards), which I feel isn't fair for the music magician. I feel like you should have 10 to choose from, but only get to learn 5 of them to your list of sorcerer spells known, totaling to 20 sorcerer spells by 20th level.]

The simulation accounted for the last 2 points. For the 1st point, just double the medians and means.

Can you really call it "Running dry" if it can

A) Be reset to to it's starting value as a bonus action once a day

B) Has a minimum of 1d4 and can still go back up from there

C) Is still useful as a d4 and has a theoretically higher chance to increase back up to 1d6 

Aberrant mind was so much more fun than psionic soul, it had so much more flavor! Please bring it back!

@fyre4000, I ran the simulations as well (1 million each). My median values match your results exactly. Woot.

BEST CLASS

The Psionic Soul's ability to eliminate the need for any and all components is crazy! I personally love it, but could see other DM's really disliking it.

Or maybye a few times per long/short rest they can chose to deal average damage if their initial damage is lower
