Lil' Charlotte

This small, diminutive doll is curiously lifelike. Thought inanimate, you sometimes get the strange sense that it is watching you.
If you kill a living creature, that creature's soul is transferred into Lil' Charlotte. As part of the Cast Spell action, you may expend one soul held within Lil' Charlotte. If you do, your next spell deals its maximum damage, and Lil' Charlotte deals 10 psychic damage to you. Lil' Charlotte can hold a total of 4 souls.
