The Monster-Eater, an OSR class

This is a class that acquires the powers of monsters by eating them. Unfortunately, you will also acquire their visibly monstrous parts, and their horrific desires. 

Level-up, and gain more flexibility in what consuming the flesh of the freshly-departed can do for you!

This class should be compatible with any OSR or D&D-like game with the standard six stats in the standard ranges, as well as things such as Levels and Hit Dice, or their equivalents.
