Gremlins rarely reach six inches in height. They are covered in greenish scales, have small bat-like wings, and their tails, back and head are often covered in rows of tiny spikes. These spikes are often black, yellow, blue or a deep blood-red in color.

Gremlins are adept at spotting gates and portals. A surprising number of these creatures use this ability to make their way to the material plane to wreak whatever havoc they can.

A Gremlin’s natural weaponry leaves much to be desired; only doing a tiny amount of damage. Their claws and teeth don’t even get scaling damage that other weapons get. Their tiny spears are covered in a poison that allows them to put others to sleep so that they may have their fun uninterrupted.

Gremlins also make for good familiars, as they are able to communicate with their masters through speech, they can sense magical gates and portals, and they can sense magic by simply touching an object. Additionally, their ability to turn invisible at will allows them to serve as spies.
