Cursed Slate

A large slate with a curse inscribed into it. It is thought that long ago this was used to place curses on someone's foes. However, after a long time absorbing the feelings of humans, it turned into a monster that indiscriminately attacks living things. Most everyone capable of using cursed slates have died out, and all documentation relating to their techniques have been lost. Only this slate remains as a memory of their ancient ways.

Resistance
