Black Imp

Trivia
When using (And maybe even ?), the Black Imp is labeled as "Portal Imp".

Behavior
The Black Imps are one of the earlier enemies that you will face up against in Risk of Rain, similar to their brethren (Imps), these kinds will also teleport, only shorter. Once close enough the Imps will teleport behind you and attack you from there. They deal a small amount of damage but move rather fast.
