Creatures with the wild magic simple template are native to regions where magic is unstable, and act as focal points for such instabilities. A wild magic creature's quick and rebuild rules are the same.
[b]Rebuild Rules: Defensive Abilities gains DR 5/— against magic weapons only; SR gains SR equal to new CR +10, or new CR +13 if the base creature already has SR; Special Attacks Wild Magic (Su) Whenever a spell that allows spell resistance fails to overcome the spell resistance of one or more wild magic creatures, it is affected as if its caster were on a plane with the wild magic planar trait. Resolve this ability after caster level checks are made to overcome the spell resistance of creatures that would be affected if the spell were to produce its normal effects, but before resolving any other effects of the spell.
