Hyounomi no Jutsu (Swallowing Ice Technique)
Ninjutsu (Hyouton) [Cold]
Rank: 4 (C-Class);
Range: Medium (20 ft. + 10 ft./2 extra chakra);
Target: One creature;

To properly perform this technique, there must be at least 2 feet of snow or ice below the target if it is Tiny or smaller, 5 if it is Small or Medium size, 10 if it is Large, 20 if it is Huge, 30 if it is Gargantuan and 50 if it is Colossal. The snow and ice underneath the target will open up and swallow the target unless it makes a Reflex save to avoid falling in the technique. A creature so buried is only partially exposed and cannot move, perform any actions other than a free action and is immobilized until it can succeed three Dexterity check (DC 18) in a row. A trapped creature suffers 10 points of Cold damage per round unless it succeeds a Str save (DC 12) or wears warm, thick clothing or fur (or is under the effects of Unki Tate no Jutsu).
