OSR: 1d500 Biological Mutations

Every good D&D game needs a huge mutation table. Ideas stolen from every free table I could find on the net, including:
Elf Maids & Octopi (indexed here).
Monster Manual Sewn From Pants (table 1 and 2)
Joeskythedungeonbrawler

Also, if you like this sort of thing, go get The Metamorphica. More mutations!

These mutations are designed to be mostly biological rather than supernatural. There's an approximately even mix of benefits, penalties, and cosmetic changes. It's not exactly balanced... but who cares?

Wizards can gain mutations through spell mishaps. Everyone else can get them via the usual routes: untested potions, octarine light, eating strange meat, and accumulating curses.
