Bomber resistance is the single worst curio perk in the game and it’s not even close.
It makes such an insignificant difference that even when you fully max it out on all 3 curios, it may not even afford you one more tick. At least that was the case the last time I tested it.
Oops. I went into a mission, and you’re right. Changing my perk didn’t work with loadout config or the crafting even when I exited and entered the pskyhanium.
