This spell creates a wall of dark water churning with violently crashing waves. The wall cannot be formed in an area occupied by creatures or objects. The wall is 2 inches thick per caster level. The churning dark water obscures vision through it so that creatures can only see up to 10 feet past it. Both sides of the wall emit a cold, stinging spray of water and the sound of loud, crashing waves that is very distracting. Spellcasters must make Concentration checks (DC 13) when within 5 ft. of the wall.

Creatures attempting to pass through the wall suffer 2d4 points of bludgeoning damage and must make an opposed Strength roll vs. the wall, which has a Strength of 20 + 1 per two caster levels. The wall violently ejects those who fail back the way they came, throwing them back 5 ft. per two caster levels. If the creature impacts a solid object as a result of being ejected, it suffers damage as if it had fallen the same distance. If the wall is ring-shaped, it only ejects creatures attempting to pass through it from the outside.

Each 10-foot length of wall has 3 hit points per inch of thickness. The wall has damage reduction 5/bludgeoning. 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.

If any 10-foot length of wall takes 30 points of fire damage or more in 1 round, that length evaporates. (Do not divide fire damage by 4, as normal for objects.)

Wall of crashing waves can be made permanent with a permanency spell. A permanent wall of crashing waves that is extinguished by fire damage becomes inactive for 10 minutes, then reforms at normal strength.
