Freeze

Feats

A water elemental's attack deals additional 2d10 cold damage on hit. After that the target must make a successful Fortitude saving throw, or start freezing, taking 2d10 cold damage per turn for the next 1d4 rounds. Whenever an enemy hits the elemental with a melee touch attack or a melee weapon without the Reach special ability, they take 2d10 cold damage and must make a successful Reflex saving throw, or start freezing the same way.
