Provided enough water exists nearby or in the air, a stellifera can psychokinetically construct a watery humanoid-shaped body as a full action and maintain this hydrobody indefinitely, including while unable to take actions or unconscious. A stellifera can dismiss this hydrobody as a standard action, and it disintegrates if he dies. The hydrobody affords the stellifera the size and reach of a Medium creature, and while unclad, it can fit through any opening the stellifera can without squeezing. While within a hydrobody, a stellifera has a Strength score 4 higher, 2 additional Hit Points, a land speed of 30 feet, a swim speed of 30 feet, and the ability to wield weapons and wear clothing and armor as a Medium creature. In addition, a stellifera in a hydrobody takes the bleed effect from only a wound or severe wound critical hit effect, is immune to gases and inhaled poisons, and gains a +4 racial bonus to Fortitude saving throws against diseases and poisons of the contact or injury types. The hydrobody slowly exchanges oxygen with the surrounding atmosphere or liquid, including environmental protections from armor, allowing the stellifera to breathe as if he were underwater. The nature of this body makes the stellifera immune to most effects of vacuum as well as atmospheric or underwater pressure. The hydrobody stores enough oxygen at one time for a stellifera to go 1 hour without oxygen exchange from his surroundings. After that time, he risks suffocation.
