Expanded Spell List
The following spells are added to the warlock spell list for you.
Awakened Mind
Starting at 1st level, 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. Additionally, the creature does not gain the ability to telepathically reply, despite you being able to speak to it.
Entropic Ward
At 6th level, 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, you 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. Additionally, your thoughts can't be read unless you allow it.
Create Thrall
At 14th level, you can use your action to touch an incapacitated humanoid. That creature is charmed by you until a Remove Curse spell is cast on it, the charm 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.
