Murtlap

The Murtlap is a rat-lie animal that has a growth on its back that resembles a sea anemone. The diet of the Murtlap is mainly crustaceans, although it will try to eat the feet of anyone who tries to step on them.

The growth on the Murtlap's back, when pickled and eaten, is proven to improve a person's resistance to jinxes and curses. Murtlap essence, another product of the creature, is know to have a regenerative effect.
