Changelings

Description
These shapeshifters are truely perplexing creatures. They assume the form of their enemy, before entering conflict, mimicing all strengths and weaknesses of their foe. In their natural form, they laugh like maniacs, before attempting to bite their foe with their sharp teeth. Upon death, Changelings dissipate into nothing. The schooled adventurer should have no problem to dispatch with these creatures.

Changelings can be encountered everywhere.
