Aquatic Elf
CommonRemaster
Ancestry Elf
You are an aquatic elf who spends most of your life underwater. You have the ability to breathe both air and water, but you cannot live indefinitely on the surface. You gain the amphibious trait, and you have a swim Speed of 30 feet. At least once a week, you must take an 8-hour period of rest underwater. If you do not, you become Fatigued, and you cannot recover from this fatigue until you rest underwater.
Traits
Amphibious
An amphibious creature can breathe in water and in air, even outside of its preferred environment, usually indefinitely but at least for hours. These creatures often have a swim Speed. Their bludgeoning and slashing unarmed Strikes don't take the usual –2 penalty for being underwater.
