Hydration

While you are an amphibious being equally as capable on land as in the water, your body requires you to return to aquatic environments at least once in a 24-hour period. You must submerge in water in order to rehydrate your water-acclimated skin.
If you fail to do this, your skin begins to crack and your gills become painful. After the first 24 hours outside of water, you take a -1 status penalty to Fortitude saves. After 48 hours, you struggle to breathe air and begin to suffocate until returned to water.
