This spell can be cast in one of three ways: as an anchored plane of ice, as a hemisphere, or as a horizontal sheet to fall upon creatures with the effect of an ice storm.

A) Ice Plane. When this spell is cast, a sheet of strong, hard ice is created. The wall is primarily defensive, stopping pursuers and the like. The wall is 1 inch thick per level of experience of the wizard. It covers a 10 foot square area per level (a 10th level wizard can create a wall of ice 100 feet long and 10 feet high, a wall 50 feet long and 20 feet high, etc.). Any creature breaking through the ice suffers 2 points of damage per inch of thickness of the wall. Fire-using creatures suffer 3 points of damage per inch, while cold-using creatures suffer only 1 point of damage per inch when breaking through. The plane con be oriented in any fashion as long as it is anchored along one or more sides.

B) Hemisphere. This casting of the spell creates a hemisphere whose maximum radius is equal to 3 feet plus 1 foot per caster level. Thus, a 7th level caster can create a hemisphere 10 feet in radius. The hemisphere lasts until it is broken, dispelled, or melted. Note that it is possible, but difficult, to trap mobile opponents under the hemisphere.

C) Ice sheet. This caster of the spell causes a horizontal sheet to fall upon opponents. The sheet covers a 10 foot square area per caster level. The sheet has the same effect as an ice storm’s hail stones – 3d10 points of damage inflicted to creatures beneath it.

A wall of ice cannot form in an area occupied by physical objects or creatures; its surface must be smooth and unbroken when created. Magical fires such as fireballs and fiery dragon breath melt a wall of ice in one round, though this creates a great cloud of steamy fog that lasts one turn. Normal fires or lesser magical ones do not hasten the melting of a wall of ice. The material component of this spell is a small piece of quartz or similar rock crystal.
