Coastal Adaptation

--- You grew up in a colony that builds structures along the coast and in the oceans, and you've adapted to life underwater. You become trained in Athletics. If you would automatically become trained in Athletics (from your background or class, for example), you instead become trained in another skill of your choice. You gain a swim Speed of 5 feet and the Amphibious trait, allowing you to breathe underwater as well as in the air. Special If you take the Swimming Specialist ancestry feat, you gain a swim Speed of 30 feet instead of 20 feet.
