On Interesting Treasure: The Wooden Brain Mask

This mask is made of wood. Dried hide of some unknown creature is stretched over and covering the face and neck, which is decorated with several black grooves. The hide has a painted line on the forehead, and then there are the five tentacle-horn projections extending above the head.

Anyone is welcome to wear this mask, the Dungeon Master is responsible for determining what heinous event occurs next. The use of a random table is suggested.

The mask sells as a curiosity ("Will you look at that thing!?") for 800 gold.
