Touched by the Depths (Su)

**Requirement**: Mordant Spire

You gain the hold breath ability (*Pathfinder RPG Bestiary 2* 298). You can expend one use of mythic power as a standard action to gain a swim speed equal to your land speed, the ability to breathe water, and tremorsense out to a range of 30 feet that only functions while under water. The ability to breathe water does not hinder your ability to breathe air. These effects last for 10 minutes per mythic tier.
