Stinger

Description:

Sometimes known as shock serpents, Stingers are similar to humanoid electric eels. They are amphibious, though their habitat ranges from the open sea, to lakes, rivers, and even swamplands. While they are intelligent, tool-using humanoids, they do not develop sophisticated societies and are only ever encountered as individuals or in small pods or hunting groups. Stingers constantly accumulate an electrostatic charge in their bodies, which will discharge when they are touched.

Special:

Whenever a Stinger is touched (as when hit with a weapon) they automatically discharge built up static electricity, effectively casting the Concussion Spell as a free action. This has no Casting Cost though it can only happen once per turn, the first time that they are touched or struck. This is an electrical attack, and metal armour does not Protect. Stingers are immune to shock damage, and are fully amphibious - able to live and breathe indefinitely in or out of water.
