With the smell of the sea and the sound of rushing waves, your body adapts itself perfectly to the aquatic environment, becoming slightly clammy to the touch. You gain the aquatic subtype and a swim speed equal to your base land speed. In this form you are perfectly amphibious, capable of breathing air or water equally.
By spending an additional 2 power points, you can adapt your body to survive even in the terrible lightless depths of the ocean trenches, becoming immune to the pressure damage. This does not, however, grant you the ability to see in those depths.
