Sithhud's Frigid Might

Feats

This creature's claw attacks deal an additional 2d10 cold damage on each hit. After that the target must make a successful Fortitude saving throw or start freezing, taking 2d10 cold damage each round until it makes a successful Fortitude save. Whenever this creature confirms a critical hit with its bite attack, it deals an additional 6d10 cold damage and the target is affected by an icy prison spell. Whenever an enemy hits this creature with a natural weapon or an unarmed strike, that enemy must make a successful Reflex saving throw or start freezing the same way.
