Racial Construct
Not living, but rather, creatures animated through arcane power, constructs like golems and elementals receive little healing from divine or psionic sources, but receive more than usual from Arcane casters.
Nothing can be done to alter this state of being, short of remorting to a different race!
Constructs receive -50% heal from divine and psionic sources and +50% from arcane sources.
This racial also grants immunity from poisons and diseases.
