Council of Thieves
Green Slime is a green, greasy algae-like slime that covers dark, moist places. It’s barely mobile and has no intelligence whatsoever, but it’s acidic mucus excretions will eat through metal and organic matter in seconds. Once the acid gets on you, it will burn for several seconds and only fire can safely get it off. It’s best to burn the slime from a distance and not touch it at all.
Being the least mobile of the oozes, Green Slime is considered the “least” slime.
