Wave

Sidebar Undersea Priests When a priest casts this spell, a wave originates from him and moves in the direction he faces, in a 60° arc. The wave is 1 foot high per level of the caster, and it travels for 60 feet plus 30 feet per level of the caster on the open sea, reaching inland for 10 feet per level of the caster. Ships caught in the wave spell's area of effect must make a seaworthiness check to avoid capsizing, though at a +30% bonus at 1st level; this bonus decreases by 5% per level thereafter, so that normal seaworthiness checks are made for a wave cast by a 7th level sea-priest. The -5% penalty is applied for every level after 7th level as well, so a seaworthiness check is made at a -20% penalty against an 11th level sea-priest's wave, which is 11 feet high and travel for 390 feet on the sea. The wave causes 1 point of damage per level of the caster to any land-based being struck by it if the wave rolls overland, but it causes no damage to swimmers on the open sea.

Wave spells are unaffected by sea or weather conditions. Thus, a wave can be made to run at a right angle to or completely counter to the direction of any other waves. Wave spells affect the surface of the water only and have no more effect on underwater creatures than naturally occurring waves.
