I cant understand the bonus system at all(
For example - Irradium Helm
Set Bonuses:
• Irradium weapons: +3% Crit Chance, +10% Rad Resist

• Immune: All Rads
It says that it gives you rads immunity but why it also gives you +10% Rad Resist? If im already immune to rads why do i need any more resistance from it?

And another one=)

I crafted EVA Arnour, it gives you immunity to Radiation, Rad Burns, Pus, and Liquid Nitrogen. But when i put this set on, status from tricorder saying that my immunity is - Radiation 1.
This set is tear 3 armour but immunity that it gives you is only first tier? So i cannot go to deadly radiation planets? Or i can feel safe at any rads lvl?
