I have issues understanding how the armors multiplier works.
i tried to put modded armors compatibility but never succeded.
maybe doing a protection based multiplayer could fix thoses compatibility issues ?

What does your file look like when it doesn't work?

i think i don't call the right items. By the way i don't see the results even if it works because i don't understand the multiplier.
