Keeper of the Current

Tracking creatures underwater is particularly challenging, but a keeper of the current can read traces of eddies in the water to follow her prey. A keeper of the current adds her level as a bonus on Survival checks to follow creatures underwater. She gains no bonus when finding or following tracks out of the water. This ability replaces track.

At 5th level and at every 3 levels thereafter, a keeper of the current can learn a spell with the water descriptor from the cleric, druid, inquisitor, or wizard spell list in place of a spell she already knows. In effect, she loses an old spell in exchange for a new one. The new spell's level must be the same as that of the spell being exchanged, and it must be at least 1 level lower than the highest-level inquisitor spell she can cast. The keeper of the current can swap out only a single spell at any given level and must choose whether to swap the spell at the same time she gains new spells known for the level. This ability alters the inquisitor's spellcasting.

At 5th level, an opponent that takes extra damage from the keeper of the current's bane or greater bane ability has its swim speed halved for 1d4 rounds. A successful Fortitude saving throw (DC = 10 + half the inquisitor's level + her Wisdom modifier) negates this effect. If the keeper of the current targets a creature already affected by this ability, its swim speed is not further reduced but the duration of the effect is extended by 1d4 rounds. This ability replaces discern lies.
