This spell creates a large mass of frozen unholy water that can be used for one of two effects.

Unholy Ice Wall: This spell creates an anchored plane of ice or a hemisphere of ice, depending on the version selected. A unHoly Ice wall cannot form in an area occupied by physical objects or creatures. Its surface must be smooth and unbroken when created. Any Creature adjacent to the wall when it is created may attempt a Reflex save to disrupt the wall as it is being formed. A successful save indicates that the spell automatically fails. Fire can melt a unHoly Ice wall, and it deals full Damage to the wall (instead of the normal half Damage taken by objects). Suddenly melting a unHoly Ice wall creates a great cloud of steamy fog that lasts for 10 minutes.

Unholy Ice Plane: A sheet of strong, hard ice appears. The wall is 1 inch thick per Caster Level. It covers up to a 10-foot-square area per Caster Level (so a 10th-level Wizard can create a unHoly Ice plane 100 feet long and 10 feet high, a wall 50 feet long and 20 feet high, or any other combination of length and height that does not exceed 1,000 square feet). The plane can be oriented in any fashion as long as it is anchored. A vertical wall need only be anchored on the floor, while a horizontal or slanting wall must be anchored on two opposite sides.

Each 10-foot square of wall has 3 Hit Points per inch of thickness. Creatures can hit the wall automatically. A section of wall whose Hit Points drop to 0 is breached. If a Creature tries to break through the wall with a single attack, the DC for the Strength check is 15 + Caster Level.

Hemisphere: The unHoly Ice wall takes the form of a hemisphere whose maximum radius is 3 feet + 1 foot per Caster Level. The hemisphere is as hard to break through as the ice plane form, but it does not deal Damage to those who go through a breach.

Any Creature that takes Damage from unHoly Water takes 1 point of Damage every time it touches or attacks the ice wall with melee attacks; extended contact with the wall (such as standing or walking on it) deals 1d6 points of Damage. Even when the ice has been broken through, a sheet of frigid unholy air remains. Any Creature that steps through it (including the one who broke through the wall) takes 1d6 points of Damage + 1 point per Caster Level (no save); half of this Damage is cold Damage, half is Damage from unHoly Water (creatures unharmed by Holy Water do not take the damage).

Unholy Ice Javelins: The spell creates a number of javelins of frozen unHoly Water in your square equal to your Caster Level (maximum 15), which hurl themselves toward one or more targets that are no more than 10 feet away from each other. You must succeed on attack rolls (one per javelin) to hit the target with the Javelin, using your base Attack Bonus + your Wisdom modifier. The javelins deal 1d6 Damage each, plus 1 point of cold Damage and 1 point of Damage from Holy Water. The javelins are destroyed by this attack.
