Special Abilities

Mutating Touch (Su) A hesper can deliver an enormous dose of radiation with a touch, triggering sudden mutations and pain in living creatures. With a successful attack against a living creature’s KAC, a hesper causes the target to sprout tumors that erupt at the beginning of its next turn, causing a random mutation (roll 1d20 on the following table) that persists for 24 hours. An affected creature can negate this transformation with a successful DC 13 Fortitude saving throw. Once a creature has been affected by a hesper’s mutating touch, it becomes immune to that particular fey’s mutating touch for 24 hours.

Reactor Sprite (Su) If a hesper spends 1 hour in close contact with a starship’s power core or another large power source (such as a fusion reactor), it can form a long-term bond. A hesper can merge with its bonded reactor, gaining fast healing 5 while it remains merged. A merged hesper is aware of what happens in the reactor’s immediate vicinity, but if the reactor is broken or suffers the wrecked critical damage condition, the hesper is immediately expelled and takes 3d6 damage. If the reactor is destroyed while the hesper is merged with it, the hesper is slain instantly (Fortitude DC 15 negates). A hesper can bond with only one reactor at a time, and forming a new bond severs its previous bond.
