After Self (Sp): Mwellrets can assume the shape of any Small or Medium-size creature. This works like alter self as cast by a 4th-level sorcerer. It can assume a new form or return to its own as a standard action.

Hypnotic Hiss (Sp): A mwellret's hiss can have a hypnotic effect on its foes. Opponents within 10 feet of a mwellret using this ability must make a Will save (DC 12) or be hypnotized as the hypnotism spell cast by a 3rd-level sorcerer.

Mwellrets enjoy attacking from the shadows or with the benefit of their alter self power. They typically begin combat by attempting to render prey helpless with their hypnotic hiss before wading in with their weapons, both natural and otherwise.

Due to their extraordinary superiority complexes, Mwellrets nearly always avoid using their shapechanging power, choosing instead to appear in the their true reptilian form, especially in a fight. Nothing is more satisfying to a mwellret than ripping out the throat of a lesser creature (which includes any creature that isn't a mwellret) with its teeth and claws.
