Morph

Spells that slightly alter a creature's form have the morph trait. Any Strikes specifically granted by a magical morph effect also gain the magical trait. You can be affected by multiple morph spells at once, but if you morph the same body part more than once, the second morph effect attempts to counteract the first (in the same manner as two polymorph effects). Your morph effects might also end if you are polymorphed and the polymorph effect invalidates or overrides your morph effect. For instance, a morph that gave you wings would be dismissed if you polymorphed into a form that had wings of its own (though if your new form lacked wings, you'd keep the wings from your morph). The GM determines which morph effects can be used together and which can't.
