This spell creates a huge, racing wall of water that destroys structures of less than the sturdiest stone construction. The size and destructive power of the wave depends on the amount of water pressure. The wave can be up to 10 feet high per level of the caster. An average river can wash away a farmstead, and an ocean can inundate an entire town. The tsunami washes away and scatters unprotected creatures with up to 3 Hit Dice, who must make a successful saving throw vs. death magic or be killed. Unprotected creatures with 4 or more Hit Dice take 3d6 points of damage per round of exposure. The tsunami has the same effect as an earthquake (see the 7th level priest spell of that name) on all structures except those made of solidly constructed stone.
The material components are the priest's holy symbol and a small stone, which is thrown into the water.
Notes: Granted by Istishia the Water Lord of the Forgotten Realms setting.
