Aliens
Celestial creatures are natives of one of the good-aligned Outer Planes.
Alignment: Alignment changes to good.
Traits: DR/evil with a value equal to creature’s CR - 10 (minimum DR 1/evil); if the creature already has DR of that value or greater, it instead gains resistance to electricity with a value equal to creature’s CR - 5 (minimum electricity resistance 1); when the creature isn’t on its home plane, it gains the extraplanar subtype.
