- n. A shapeshifter who can assume the shape of a rat.
Wanted: 1 artistically-inclined male bi/gay wererat.
Like an apparition, there stood in the midst of the melee a giant saber-toothed tiger, its jaws dripping blood from the wererat it had just bitten in half.
This assumes your DM allows you to remain a PC, mind you, and you might not like to change your alignment (but that still leaves wererat as a lycanthrope option).
