Pact of the Great Old One

Your patron is a mysterious entity whose nature is utterly alien — incomprehensible to mortal minds in its full scope. Beings of this sort include Ghaunadaur, Tharizdun the Chained God, Dendar the Night Serpent, and entities from beyond the known planes whose true names are unpronounceable. The Great Old One might be unaware of your existence, or it might be intimately interested in you for reasons you cannot fathom. Either way, its power seeps into you, and the knowledge it grants is as unsettling as it is potent.

Awakened Mind

1st-level Pact of the Great Old One feature

Starting at 1st level, your alien knowledge gives you the ability to touch the minds of other creatures. You can communicate telepathically with any creature you can see within 30 feet of you. You don't need to share a language with the creature for it to understand your telepathic utterances, but the creature must be able to understand at least one language.

Entropic Ward

6th-level Pact of the Great Old One feature

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

10th-level Pact of the Great Old One feature

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

14th-level Pact of the Great Old One feature

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.
