SQ change shape (any humanoid as a swift action, but always retains one serpentine trait that negates the bonus to Disguise checks; alter self)

Poison (Su) The xacarba can choose between three poisions. The save DC of each is Constitution-based. Bite:

Redirect Spell (Su) Any creature that attempts to cast a spell within 30 feet of a xacarba must cast the spell defensively. If the caster fails the concentration check to do so (or if the caster opts to not cast defensively), the xacarba can choose the target of the spell as a immediate action. The new target must be a legal target—if there's no legal alternative target to choose from, this ability cannot be used.
