Wave Strike (Su)
Source: Advanced Class Guide, p. 46
As a standard action, the shaman can perform a melee touch attack that drenches a creature and pushes it away. The opponent takes 1d6 points of nonlethal damage + 1 point for every 2 shaman levels the shaman possesses and is pushed 5 feet directly away from the shaman. This movement does not provoke attacks of opportunity. A shaman can use this ability a number of times per day equal to 3 + her Charisma modifier. At 11th level, any melee weapon she wields is treated as if it had the quenching special ability.
