Lil' Charlene

No matter where Lil' Charlene is when you go to bed, Lil' Charlene is right beside you when you wake up.
If you kill a non-undead creature, that creature's soul is transferred into Lil' Charlene. As part of the Cast Spell action, you may expend one soul held within Lil' Charlene. If you do, your next spell deals its maximum damage, and Lil' Charlene deals 10 psychic damage to you. Lil' Charlene can hold a total of 5 souls.
