By forming ice around a Medium-sized or smaller creature at high speed, the user is able to entrap a creature in the ice. If the creature fails its Dex save, it will be forced into an ice prison for the duration of this technique. A medium-sized creature will start suffocation on its next turn and can only break free of the prison by succeeding a str check (DC 30). A Small or smaller creature will start suffocating in 1d4+1 rounds and can damage the prison from the inside or attempt to break free with the str check. The Ice Prison has no hardness and 35 hit points, and if a creature outside the prison attempts to break it, the trapped creature will suffer half the damage of the attack that finally tore it down. The trapped creature can still see and be seen, cannot perform techniques that require either mobility, hand seals or half seals and counts as flat-footed until it takes an action in combat.

Expendable Components: A large (at least 250 sq. ft.) source of snow or ice nearby.
