Badb

Mimicry. The raven can mimic simple sounds it has heard, such as a person whispering, a baby crying, or an animal chittering. A creature that hears the sounds can tell they are imitations with a successful DC 10 Wisdom (Insight) check.

Badb’s Boon: If The Badb is able to obtain a piece of a humanoid or fey target such as a hair or chunk of flesh, the warlock is able to perform a ten minute ritual to enter that target’s dream. The hair or flesh is destroyed in the process. The warlock is able to interact with the target and has advantage on intimidation and deception checks within the dream.

Beak. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 1 piercing damage.
