Half-Mer-Elves

Half-mer-elves are not as limited as their elvish parents, having human legs. They are required to immerse themselves in water for at least one hour a day. They are able to breathe water as easily as air. They do have slightly fishy characteristics, such as gill slits that appear while they are immersed, sections of their body covered in scales, and webbed feet and hands. Most encounters with "mer-elves" are actually encounters with these half-breeds.
They gain the following racial abilities:
• Abilities: -4 Constitution, +2 Dexterity
• Amphibious (Ex): Half-mer-elves can breathe both air and water.
• Immersion: Half-mer-elves must completely immerse themselves in water for 1 hour per day. They suffer 1 point of temporary Constitution damage for every four hours they fail to immerse themselves.
