This spell creates a wave of hardened ice which the wizard actively directs. After casting, the wizard simply taps the ground to activate the spell. The wave of ice begins where the wizard taps the ground, and reaches its full dimensions after advancing only 10 feet. It travels at a speed of 40 feet per round. The crest of the wave is 10 feet high and 15 feet wide; after the crest of the wave has passed, the remaining "trail" is only 3 feet high.
Creatures coming into contact with the crest suffer 2d6 points plus 1 point damage per level of the wizard, or half this amount if the creature is cold-using (in general, cold-dwelling creatures take half damage from this spell, rounded down, and cannot suffocate as a result of this spell). In addition, creatures of less than large size must save against paralysation or be buried under the crest. Buried individuals take an additional 1d3 points of cold damage each round and must initially make another saving throw against paralysation or start to suffocate under the ice (use the rules for drowning). Trapped creatures may break free, taking 1 more point of damage per level of the wizard from sharp ice.
The crest of the wave can be disrupted by 30 or more points of fire damage, or negated by a wall of fire in any case. At the end of the spell duration, the crest of the ice wave immediately loses all momentum and melts; the spell will cause no more damage, and trapped creatures can easily break free taking no damage. The material components for this spell are a steel pin and a glass of icewater.
