The Feigning Fey

A twisted, otherwordly entity masquerading as a reigning Archfey. Basically, the power and mystery of The Great Old one but the presentation and whimsy of The Archfey. 

Awakened Mind

Starting at 1st level, your alien knowledge gives you the ability to touch the minds of other creatures. As a bonus action, choose one creature you can see within 30 feet of you. You and the chosen creature can speak telepathically with each other while the two of you are within a number of miles of each other equal to your Charisma modifier (minimum of 1 mile). To understand each other, you each must speak mentally in a language the other knows.

The telepathic connection lasts for a number of minutes equal to your warlock level. It ends early if you are incapacitated or die or if you use this ability to form a connection with a different creature.

Entropic Ward

At 6th level, you learn to magically ward yourself against attack and to turn an enemy's failed strike into good luck for yourself. When a creature makes an attack roll against you, you can use your reaction to impose disadvantage on that roll. If the attack misses you, your next attack roll against the creature has advantage if you make it before the end of your next turn.

Once you use this feature, you can't use it again until you finish a short or long rest.

Thought Shield

Starting at 10th level, your thoughts can't be read by telepathy or other means unless you allow it. You also have resistance to psychic damage, and whenever a creature deals psychic damage to you, that creature takes the same amount of damage that you do.

Create Thrall

At 14th level, you gain the ability to infect a humanoid's mind with the alien magic of your patron. You can use your action to touch an incapacitated humanoid. That creature is then charmed by you until a Remove Curse spell is cast on it, the charmed condition is removed from it, or you use this feature again.

You can communicate telepathically with the charmed creature as long as the two of you are on the same plane of existence.
