Radioactive
Traits
Radiation Immune In radioactive zones, creatures might adapt and become immune to certain levels of radiation. You can give a creature radiation immunity without it counting against that creature’s number of special abilities. |
Senses Radiation can cause weird mutations. Creatures native to radioactive regions might have unusual forms of blindsense or blindsight, perhaps allowing them to perceive things that lack radioactivity. |
Skills Survival |
Any terrain might be radioactive, but such territory is often desolate like a desert.
