Quote:no, only flat reduction can take an opponent's resists into the negatives.
So pretty much only morgana/soraka/amumu/fiddle together will get somebody into negative Mres.
I have yet to see negative armor.
Edit: guess not, thanks for answering
Level 1 Sona has bad resists, could we get her to negative?
So, a few notes that may have been covered, or may have been misconstrued.
The order of effects are as follows:
1. Flat Reduction
2. Percentage Reduction
3. Percentage Penetration
4. Flat Penetration
Your armor value is recalculated based on those rules if its base changes while the debuffs are present. All percentage effects stack multiplicatively.
Penetration can only bring the mitigation stat to 0, Reduction can go beyond. Negative mitigation gives you a damage amp equal to the damage reduction you would have gained if you had positive mitigation with the same magnitude.
Armor Penetration is a buff that lets a single champion do more damage to anyone with armor.
Armor Reduction is a debuff that makes a single champion take more damage from physical damage.
Quote:What does this mean for reduction then? That there are wasted stats if you happen to have both % reduction and flat reduction on the same target, much like how it used to be with penetration? Would there be any huge gameplay implications if these were reversed as well?
I can't speak to whether the game would be better or not if we switched them, but it'd actually be a non-trivial change to make because of how the system is set up right now. I'd rather not get into whether it "should" or not; my focus is telling people what "is".
Quote:I also thought it was % reduction before flat. That's what the League of Legends Wikia says and it goes into detailed examples:
It is definitely not the case now.
Quote:Xypherous said that reductions counted what debuff that was placed first.
IE, % then Flat would be different from Flat then %.
All flats are collected additively and applied.
All %'s are collected multiplicatively and applied.
Edit: for Reductions, not Penetrations. Just to be clear.
