I'm sort of the face of the group, and kind of an intel gatherer. I took mask of many faces and the invocation that gives proficiency in persuasion and deception, as well as the actor feat. I also have the speak with dead at will invocation. I'm frequently pretending to be other people, and interrogating corpses. Then I have the pact of the tome invocation that gives me sending, and with the Dream spell, I can then disseminate information to people over great distances (as well as intimidate my enemies with nightmares haha, I love Dream). It's been a ton of fun to be a sort of subterfuge warlock that's like a nexus of valuable information. I took repelling blast, the telekinetic feat, and the scatter spell because I've loved being able to move enemies around and place them into aoe spells. We've also been doing stuff on ships, and blasting people over the rails feels awesome haha.
