Like Statuses, What if SOME Armors gave a negative resistance towards other damages, for example, Skolver Cap/Coat have a Negative resistance to Shadow Damage. But don't give ALL the armor's negative resistances otherwise it'll be too much. So when wearing a Wolver cap, there is no penalty however once it hits 3* it would then get a penalty of low Shadow resistance. Ash Tail would be -2 and Skolver -3. Incase you don't know what I mean buy -2 and -3, I mean the amount of shadow resistance you would normally get but instead of resistance it's a penalty. So Skolver would have -High Shadow Resistance..(Also other ideas would be Perfect Mask of Seerus Piercing Penalty and Chaos Shadow Penalty, that would screw up Clones in FSC).
Firstly, I'll explain it better...
UV'S:
Shadow Low - 3*
Shadow Medium - 4*
Shadow High - 5*
So When you would equip a Skolver Cap with Shadow High, It would have no penalty. If it had Shadow Medium, it would have -1 Penalty.
NOTE: This has been updated so it's not as-mean.
No, it's too evil. Negatives should be between med and high.
