Obliviax
Obliviax, or memory moss, is an evil black moss with the ability to steal memories, even memorized spells.
It grows in small patches and must have sunlight to spur reproduction by spores, though it needs no light for growth. It prefers a balance of wet and dry, and cannot abide cold temperatures. The moss senses intelligent creatures within 60 feet; it chooses one, preferring wizards, then other spellcasters. This victim must make a saving throw vs. spells or lose all memory of the last 24 hours. The obliviax continues to attack once per round until it succeeds and then makes no more attacks for 24 hours. If an obliviax with stolen memories is attacked, it forms part of itself into a tiny moss imitation of the creature whose memories it stole. This mossling remains attached to the parent moss and defends it by casting stolen spells. To regain stolen memories, a victim must eat the living obliviax, which takes one round. If a saving throw vs. poison is successful, the eater regains all stolen memories and spells; if the saving throw fails, the eater becomes very ill for 3d6 turns. Extra memories and spells can be gained by eating obliviax which has fed on someone else recently. Spells can be used by the eater, but all such memories fade within a day. A potion of forgetfulness can be distilled from obliviax, and its spores can be used to make an elixir to restore the memories of the forgetful or senile.
