Polymorph (Small Water Elemental)

The target creature becomes a small water elemental. It gains a +2 size bonus to its Constitution, a +4 natural armor bonus, resist cold 20, and vulnerability to fire. Its movement speed is reduced by 10 feet. It also gains one 1d6 slam attack and the freeze ability. Freeze: A water elemental deals 1d4 cold damage in addition to damage dealt on a successful hit in melee. Those affected by the freeze ability must also succeed at a Reflex save or start freezing, taking 1d4 damage each round for an additional 1d4 rounds. Creatures that hit a freezing creature with natural weapons or unarmed attacks take cold damage as though hit by the freezing creature and must make a Reflex save to avoid freezing.
