The Great Old One

Expanded Spell List

The Great Old One lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Awakening Mind

Starting at 1st level, your alien knowledge gives you the ability to touch the minds of other creatures. You can telepathically speak to any creature you can see within a number of feet equal to 20 times your Warlock level. 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.

Starting at 6th level, you no longer need to see the creature to speak with it using this feature.

Entropic Ward

At 6th level, you learn to magically ward yourself against attack by assaulting the mind of your attacker. When a creature makes an attack roll against you, you can use your reaction to impose disadvantage on all attack rolls made against you by that creature until the start of your next turn.

You can use this feature a number of times equal to your proficiency bonus. You regain these uses when you finish a 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 psychic damage equal to the damage dealt prior to resistances being applied. Ex: If a creature deals 35 psychic damage to you, you will take 17 and that creature will take 35.

At 14th level, your psychic damage resistance changes to immunity.

Awakened Mind

Starting at 10th level, you can use your action to bind yourself to a creature within range of your Awakening Mind feature. While this feature is in effect, you and the target can communicate telepathically through the bond whether or not you have a common language. The communication is possible over any distance, though it can't extend to other planes of existence. This bond lasts until you end it as an action. You can be bound to a number of creatures equal to your proficiency bonus divided by two (rounded down).

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 and views you as a close friend and ally until a remove curse spell is cast on it or the charmed condition is removed from it. You can have a number of humanoids charmed equal to your proficiency bonus divided by three (rounded down).

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

Additionally, once per long rest, you may expend one of your Mystic Arcanum to cast the Dominate Person spell using the spell level associated with that Mystic Arcanum (ex. You may expend your 8th level Mystic Arcanum use for the day to cast Dominate Person at 8th level).
