Poison Eater

The Poison Eater is a life elemental in the form of a snake around three feet long with golden scales.
They're pretty harmless unless you're poisonous or venomous, in which case they're somewhat aggressive. If you've been poisoned, they'll bite you and suck the poison out to eat it. The problem is that the more potent the poison or venom, the longer it takes them to digest, and they can only deal with one poison at a time. If they're digesting a poison, they have a line of black scales along their back.
