This mod makes resistance and weakness stack instead of applying only the strongest effect!

In vanilla, multiple sources of resistances and weaknesses do not stack nor do they cancel each other out. The strongest source of resistance will override all weakness.

The selected effect is in the order of: Very Resistant > Resistant > Slightly Resistant > Immune > Very Weak > Weak > Slightly Weak > Normal

(https://valheim.fandom.com/wiki/Resistance)

This mod change resistance and weakness into additive calculation making it stackable, and make those numbers for resistance and weakness adjustable

For example, with this mod's default setting
RootArmor (pierce -30%) + BerserkerMead (pierce +30%) + BonemassPower (pierce -15%) = pierce -15% (Player would get 85% damage for pierce)
FeatherCape (Fire +45%) + BarleyWine (Fire -30%) = fire +15% (Player would get 115% damage for fire)

Mob's resistance and weakness also get affected.

For example, with this mod's default setting
Troll would get 100%+30% = 130% pierce damage (weak to pierce)
Bjorn would get 100%-30% = 70% from pierce (resistant to pierce)
