Radiation Resistance cuts radiation damage by up to 50%. Radiation zones punish unprepared visitors — this passive (plus rad-resist cores like Crystal Matrix) makes hot ground farmable.
Abilities are permanent passives bought with ability points — no cooldowns, no activation, they simply always apply.
