Crashing Waves

This is a Hex — a class feature gained through that class's own talent choices, not a feat you pick through normal feat selection.

The force of a waves shaman's water spells can bring even the mightiest of foes to the ground. When the shaman casts a spell with the water descriptor, she does so at 1 caster level higher. If that spell deals damage, the target must succeed at a Fortitude saving throw or be knocked prone. At 8th level, the shaman casts water spells at 2 caster levels higher. At 16th level, her ability to knock creatures prone extends to any spell that deals damage.
