The Way of Vell-os

This is a subclass based off of an old Ambrosia Software game, Escape Velocity Nova.  I thought it would be a fun thought experiment to translate content from such a different style of game to D&D, so I gave it my best shot.  I hope it came across well!

Rank T4

3rd-level the Way of Vell-os feature

You harbor a wellspring of psionic energy within yourself. This energy is represented by your Psionic Energy dice, which are each a d6. You have a number of these dice equal to twice your proficiency bonus, and they fuel various psionic powers you have, which are detailed below.

Some of your powers expend the Psionic Energy die they use, as specified in a power’s description, and you can’t use a power if it requires you to use a die when your dice are all expended. You regain all your expended Psionic Energy dice when you finish a long rest. In addition, as a bonus action, you can regain one expended Psionic Energy die, but you can’t do so again until you finish a short or long rest.

When you reach certain levels in this class, the size of your Psionic Energy dice increases: at 5th level (d8), 11th level (d10), and 17th level (d12). The powers below use your Psionic Energy dice.

Hostility Sense.  As an action, you can cast Detect Thoughts, requiring no spell components when you do so.  While casting the spell in this manner and reading either the surface or deeper thoughts of a creature, you may communicate telepathically with that creature.  You do not need to share a language with the creature to be able to communicate in this manner.  Once you take this action, you can’t do so again until you finish a short rest, unless you expend a Psionic Energy die to take it again.

Flower of Spring.  As an action, choose one creature or object within 30 feet, or 150 feet while in Dart, Arrow or Javelin and in space, and expend a Psionic Energy die.  If the target is of equal or lesser size than you, it must make a Strength saving throw against your Ki save DC or take 2 Psionic Energy dice of force damage and be pulled 15 feet closer towards you.  On a successful save, the target takes half damage and isn't pulled.  If the target is larger than you, or cannot be moved, on a failed save you are pulled 15 feet closer towards the object instead.  This counts as taking the Attack action in regard to your bonus action unarmed strike and Flurry of Blows.

Telekinetic Boost.  When you use a bonus action to activate your Step of the Wind feature, you may additionally expend one Psionic Energy dice to increase your base movement speed by an equal amount as your Unarmored Movement bonus until the start of your next turn, or by 10x while in space and in a Dart, Arrow or Javelin.

Rank T3

6th-level Way of Vell-os feature

Your mental training has led you to greater potential, resulting in the use of new abilities.

Summer Bloom.  As an action, choose one creature or object within 45 feet, or 225 feet while in Dart, Arrow or Javelin and in space, that you can see and expend one Psionic Energy die.  They must make a Constitution saving throw against your Ki save DC or take 3 Psionic Energy dice force damage on a failed save, or half as much on a successful save.  This counts as taking the Attack action in regard to your bonus action unarmed strike and Flurry of Blows.

Create Dart.  As an action, you project sculpted psionic energy around yourself.  You become encased in a size Medium vehicle called a Dart. Piloting the ship requires no action on your part, as it is an extension of your mental landscape.  The Dart possesses the following properties:

• It has an AC equal to your AC without any bonus from armor or a shield.
• It has a number of hit points equal to 3 times your Monk level; However, if the Dart is destroyed due to dropping to 0 hit points, any excess damage carries over to your hit point total. You also gain a number of temporary hit points equal to your Wisdom modifier at the start of each of your turns, or twice that at 11th level. 
• It has a flying speed equal to your movement speed; However, you cannot take any movement independent of the Dart.
• At the start of your turn, you can choose to enter or exit a trance-like state.  Doing so causes you to become incapacitated, however any time spent in this trance does not count towards the total time the Dart can exist, nor towards time required before you must rest.  Furthermore, if the ship is in space and no other objects weighing 1 ton or more are within 1 mile of it, you can move fast enough to travel 100 million miles in 24 hours.  You remain incapacitated until the end of the first turn where you return to normal speed.
• You have total cover from any effect originating outside of the Dart but cannot take any actions other than those granted by this subclass, dash, disengage, dodge Step of the Wind, Patient Defense, Diamond Soul and Empty Body while the Dart is manifested.  The Dart benefits from any passive Monk feature you have gained, such as Evasion or Diamond Soul.
• You can perceive your surroundings using any senses you have as if the Dart was not there.
• Once on each of your turns, you can use Flower of Spring or Summer Bloom without expending a Psionic Energy die by reducing the number of damage dice rolled by 1.
• Your body enters into a state of suspended animation.  You cannot control your body while in this state, only the Dart.  All of your equipment remains on your form; however, you cannot activate any of it while inside the Dart, and any passive effects do not extend to the Dart.  Furthermore, you do not need to breathe or consume food while in this state.  You are, however, unable to rest while piloting the ship.

You can project the Dart for up to 1 hour at a time or until its hit points are reduced to 0, at which point it dissolves into motes of psionic light.  Once you create either a Dart, Arrow or Javelin you cannot create another until you take a long rest, unless you spend three Psionic Energy dice to create a Dart.

Rank T2

11th-level Way of Vell-5-foot feature

Your mental training has led you to greater potential, resulting in the use of new abilities.

Autumn Petal.  As an action, expend two Psionic Energy dice to project a line of pure energy 60 feet long, or 300 feet while in Dart, Arrow or Javelin and in space, and 5 feet wide in a direction you choose.  Any creatures in this line must make a Dexterity saving throw against your Ki save DC or take 3 Psionic Energy dice force damage on a failed save, or half as much on a successful save.  Objects incapable of movement automatically fail this saving throw.  This counts as taking the Attack action in regard to your bonus action unarmed strike and Flurry of Blows.

Create Arrow.  When you would take an action to create a Dart, you can instead create a size Large vehicle called an Arrow.  You cannot create this vehicle if there is not enough space for it.  Piloting the ship requires no action on your part, as it is an extension of your mental landscape.  The Arrow possesses the following properties:

• It has an AC equal to your AC without any bonus from armor or a shield.
• It has a number of hit points equal to 4 times your Monk level; However, if the Arrow is destroyed due to dropping to 0 hit points, any excess damage carries over to your hit point total. You also gain a number of temporary hit points equal to twice your Wisdom modifier at the start of each of your turns. 
• It has a flying speed equal to your movement speed, however you can only apply half of the value of your Unarmored Movement (rounded down to the nearest multiple of 5) while piloting the Arrow; However, you cannot take any movement independent of the Arrow.
• At the start of your turn, you can choose to enter or exit a trance-like state.  Doing so causes you to become incapacitated, however any time spent in this trance does not count towards the total time the Arrow can exist, nor towards time required before you must rest.  Furthermore, if the ship is in space and no other objects weighing 1 ton or more are within 1 mile of it, you can move fast enough to travel 100 million miles in 24 hours.  You remain incapacitated until the end of the first turn where you return to normal speed.
• You have total cover from any effect originating outside of the Arrow but cannot take any actions other than those granted by this subclass, dash, Step of the Wind, Diamond Soul and Empty Body while the Arrow is manifested.  The Arrow benefits from any passive Monk feature you have gained, such as Evasion or Diamond Soul.
• You can perceive your surroundings using any senses you have as if the Arrow was not there.
• Once on each of your turns, when you would use Flower of Spring, Summer Bloom and Autumn Petal, you can choose to reduce the number of dice expended and damage dice rolled by 1, instead of their usual cost and damage.
• Your body enters into a state of suspended animation.  You cannot control your body while in this state, only the Arrow.  All of your equipment remains on your form; however, you cannot activate any items while inside the Arrow, and any passive effects do not extend to it.  Furthermore, you do not need to breathe or consume food while in this state.  You are, however, unable to rest while piloting the ship.
• As an action, you can choose to load or unload either two willing size Small creatures, one willing size Medium creature or up to 500 pounds of cargo, as long as it fits within a 5-foot cube, to or from a space within 5 feet of the Arrow.  While a creature or object is being transported in this manner, it is considered petrified although its weight does not change and has total cover from any effect originating from outside of the Arrow.

You can project the Arrow for up to 1 hour at a time, until you dismiss it as an action or until its hit points are reduced to 0, at which point it dissolves into motes of psionic light.  Once you create either a Dart, Arrow or Javelin you cannot create another until you take a long rest, unless you spend five Psionic Energy dice.

Rank T1

17th-level Way of Vell-os feature

Your mastery over the Vell-os arts has reached its peak, resulting in the use of new abilities.

Winter Tempest.  As an action, expend one Psionic Energy die to begin concentrating, focusing energy into a singular point.  As long as you do not lose concentration, you can choose one creature or object within 120 feet, or 360 feet while in Dart, Arrow or Javelin and in space, as an action on a subsequent turn and force it to make a Constitution saving throw against your Ki save DC or take 3 Psionic Energy dice worth of force damage.  As part of the same action on cast, you can expend up to two additional Psionic Energy dice and 5 Ki points, with each Psionic Energy die increasing the damage by 2 dice worth and each ki point by 1.

Objects and structures hit by this ability take double damage.

Create Javelin.  When you would take an action to create a Dart, you can instead create a size Huge vehicle called a Javelin.  You cannot create this vehicle if there is not enough space for it.  Piloting the ship requires no action on your part, as it is an extension of your mental landscape.  The Javelin possesses the following properties:

• It has an AC equal to your AC without any bonus from armor or a shield, and a damage threshold of 10.
• It has a number of hit points equal to 5 times your Monk level; However, if the Javelin is destroyed due to dropping to 0 hit points, any excess damage carries over to your hit point total. You also gain a number of temporary hit points equal to twice your Wisdom modifier at the start of each of your turns. 
• It has a flying speed of 30 feet; However, you cannot take any movement independent of the Javelin. 
• At the start of your turn, you can choose to enter or exit a trance-like state.  Doing so causes you to become incapacitated, however any time spent in this trance does not count towards the total time the Javelin can exist, nor towards time required before you must rest. Furthermore, if the ship is in space and no other objects weighing 1 ton or more are within 1 mile of it, you can move fast enough to travel 100 million miles in 24 hours.  You remain incapacitated until the end of the first turn where you return to normal speed.
• You have total cover from any effect originating outside of the Javelin but cannot take any actions other than those granted by this subclass, Step of the Wind, Diamond Soul and Empty Body while the Javelin is manifested.  The Javelin benefits from any passive Monk feature you have gained, such as Evasion or Diamond Soul.
• You can perceive your surroundings using any senses you have as if the Javelin was not there.
• Once on each of your turns, when you would use Flower of Spring, Summer Bloom and Autumn Petal, you can choose to reduce the number of dice expended and damage dice rolled by 1, instead of their usual cost and damage.
• Your body enters into a state of suspended animation.  You cannot control your body while in this state, only the Javelin.  All of your equipment remains on your form; however, you cannot activate any of it while inside the Javelin, and any passive effects do not extend to the Javelin.  Furthermore, you do not need to breathe or consume food while in this state.  You are, however, unable to rest while piloting the ship.
• As an action, you can choose to load or unload either eight willing size Small creatures, four willing size Medium creature or up to 2000 pounds of cargo, as long as it fits within a 10-foot cube, to or from a space within 5 feet of the Javelin.  While a creature or object is being transported in this manner, it is considered petrified although its weight does not change and has total cover from any effect originating from outside of the Javelin.

You can project the Javelin for up to 1 hour at a time or until its hit points are reduced to 0, at which point it dissolves into motes of psionic light.  Once you create either a Dart, Arrow or Javelin you cannot create another until you take a long rest, unless you spend eight Psionic Energy dice.
