Does negative defense reduce piercing stat damage?

With the new armor sets, it’s possible to get negative defense
AP does more damage the higher your opponents defense (which is bs like why should your damage depend on your opponent’s armor build excluding resistance)
So does negative defense = attacks with AP armor stat doing less dmg?

If the wiki is correct then yes


if someone with 42% AP attacks someone with 2004 total hp and 931 defense it will deal 9,11 extra dmg
42x931/(789-931)/4

Now, if someone with the same amount of AP attacks someone with 789 total hp and -284 defense, then they will deal -2,77 “extra” dmg
42x(-284)/(789-(-284)/4

unless the value is clamped to be positive

Yeah, thats what I meant by “if the wiki is correct”
It didnt mention anything about it being clamped to be positive

@Meta is this real
