As a standard action, you can emit an aura of low-level
radiation. Creatures within 5 feet of you must succeed at a
Fortitude save or be sickened. A sickened creature recovers as
soon as it moves out of your aura, and a creature that succeeds
at its saving throw is immune to your radiation for 24 hours.
This is a poison effect (see page 415). The radiation lasts for 1
round or until you leave photon mode.
When you are attuned or fully attuned, the size of your aura increases to 10 feet.
