Okay, I have just created a sorcerous origin for sorcerers who wish to have fey based powers. At first I was planning on making a general fey ancestry, similar to the Archfey Warlock, but I instead decided to split it into two different subclasses, the Seelie Born and the Unseelie Blood. I would love feedback for this subclass if you can give it. I gave it a spell table, similar to the Clockwork Sorcerer, just to give them a bit more of the seelie theme. Thanks for reading. 

Base Class:Sorcerer

Your innate magic comes from the aloof magic of the Feywild. An ancestor may have been blessed for aiding the Seelie Court in difficult times, spent time in the Feywild after traveling through a fey-crossing and mingled with seelie fey, or you could be descended from a seelie fey from the Feywild. Though you could be a Seelie Born due to your lineage, you could also have been changed in someway on your own. You could have had a child with a fey, been charmed for years or decades by a seelie, or been infused with the blood of a seelie fey.

Seelie Magic

You learn additional spells when you reach certain levels in this class, as shown on the Seelie Spells table. Each spell counts as a sorcerer spell for you, but it doesn’t count against the number of sorcerer spells you know. These spells can’t be replaced when you gain a level in this class.

Seelie Spells

Sorcerer   Level	Spells
1st	charm person, color spray
3rd	mirror image, misty step
5th	hypnotic pattern, nondetection
7th	compulsion, polymorph
9th	geas, modify memory

Aloof Nature

Starting at level 1, when a creature uses a Wisdom (Insight) check to try to determine your emotions or intentions, they make the check at disadvantage. 

When you reach 3rd level, you can cast the misty step using 2 sorcery points or by expending a spell slot. When you cast it using sorcery points, the distances you may teleport becomes 60 feet. 

Seelie Blood

At 1st level, you gain resistance to psychic damage and advantage on saving throws against effects that would charm you. 

Faerie's Luck

Starting at level 6, when a creature succeeds on a saving throw against a spell you cast, as a reaction, you may expend 3 sorcery points to force them to reroll the saving throw at disadvantage. 

Twisted Fey

When you gain this feature at 14th level, you can manipulate the environment around you to become more like the Feywild. A brief image of the wooded lands of the Feywild is projected around you, distorting distance and time. As an action, you can create a 30 foot radius area around you that takes on some properties of the Feywild. This area becomes difficult terrain while creatures are moving closer to you, but they move twice the normal distance their movement would allow while moving away from you in this area. Additionally, at the start of each round after you use this ability, each creature must reroll initiative. 

Once you use this feature, you cannot use it again until you finish a long rest, or expend a 3rd-level spell slot or higher to regain one use of it. 

Beguiling Charm

At level 18, your mastery over the charming powers of the seelie fey allow you to beguile masses of creatures and be protected from the charms of fey creatures as well. You gain immunity to the charmed condition when you gain this feature. 

Additionally, you may use an action to charm creatures around you. Each creature of your choice within 60 feet of you must succeed on a Wisdom saving throw against your spell save DC, or become charmed. For the next minute, or until they succeed on the saving throw, a charmed creature regards you as an ally and does as you command it. If you give no orders to it, it simply does nothing on its turn. A charmed creature gets to repeat the saving throw whenever it takes damage, and at the end of each of its turns.

Once you use this feature, you cannot do so again until you take a long rest or expend 7 sorcery points.
