Bio-Indefinite

This unit cannot gain or lose more than 1 health at a time (except during promotion). If a non-damage effect would defeat it, or if it would be forced to return it to its fortress, it instead loses 1 health and is returned to a valid perimeter hex on its starting isle (or the closest possible hex to the perimeter if no valid hexes are available).
