Inspired by old official works of previous editions, this labour of love shall grant you the opportunity to actual play one of the more notorious monsters out of Monster Manuals and other works!
The monster is a plain and strong class which emphasizes high hit points and weird abilities derived from their subclass, that define their roles (sometimes more obvious, sometimes not). They use a ressource called "Surge" of which your character has a certain amount (for ease's sake, twice as your proficiency bonus). This ressource not only fuels the monsters more specific abilities, like a Beholder's Eye Rays or a Drider's Spellcasting, but they also grant more generalized abilities you can find in the classes main pages.
