Ladryth's Boon (GOO)

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.

Awakened Mind

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

You also gain the ability to tap into the knowledge of your patron. Giving you expertise on history checks.

Entropic Ward

At 6th level, you learn to magically ward yourself and your allies 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.

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 gain advantage on saving throws against psychic damaging spells. 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 under your control until a remove curse spell is cast on it, the charmed condition is removed from it, or you use this feature again. If you want to make the creature do something it otherwise would never do, you need to succeed on a persuasion check. You can communicate telepathically with the charmed creature as long as the two of you are on the same plane of existence.
