Aura of Exposure (Su) Whenever a non-daemon creature within a physodaemon's 30-foot-radius aura is dealt acid, cold, electricity, fire, or sonic damage, that creature takes damage as if it had no resistance to acid, cold, electricity, fire, or sonic damage. Any immunity that creature has to acid, cold, electricity, fire, or sonic damage still applies, as normal.

Swarmwalking (Su) A physodaemon is immune to damage or distraction effects caused by swarms.
