Damage Reduction Sequence/Calculations

Community General Discussion
1

Hello all with essences, bubbles, armor, blocking I am trying to figure out if there is an official sequence for how incoming damage is calculated.

For example on a Prot Paladin if a 100k damage spell is incoming the Paladin can block the spell reducing the damage first then what is left will get absorbed by the various bubbles, Nullbarrier, resounding protection etc.

However where does Versatility, Mastery Dmg Reduction from standing in Conc and other defensive come in?

I know damage reduction is not additive so is every defensive reduction calculated before Absorbs? If you have multiple sources doesn’t that make Absorb bubbles way more effective?

Anyone have some good links or math explaining some examples on how this would work with a 100k incoming spell and 100k physical would be great.

Thanks

I think biggest damage reduction is always applied first, to the smallest damage reduction. Than absorbs are applied, afterwards. Each absorb though, as for their order, I think is completely dependent on the absorb.

I tried finding ways to make Shield of Vengeance break before Power Word: Shield, applying it before, applying it after, but I could never get it to break first. It might be alphabetical order? But I don’t know for sure, tbh.

Thanks for the response yea I am curious and I have read and googled for awhile and there isn’t really anything up to date. I only was able to find out that blocked damage is calculated first before absorbs.

Now it would be handy to know since I have 3 Absorb bubbles and multiple damage reduction sources. I am trying to look at theory crafting certain builds for highest EHP in different situations.

Actually, I think the order of damage reductions doesn’t matter, come to think of it. Regardless of the order, they always seem to result in the same overall reduction.

Absorbs though, I’m certain are alphabetically chosen first. If you have multiple absorb effects, mind going testing and see which one takes damage first? And whichever one takes damage first, take that one out for the second test, to see which is the second one to take damage.

Also, if you have specific damage absorbs, like Nullification Dynamo, it would be worth testing to see if it takes damage before something lower on the alphabetical list, that absorbs all damage. I mean logically it should, but who knows, tbh. Idk if alphabetically is even how you determine absorb priority. I’m just assuming based on my limited testing, lol.

Yea I will have to get someone in a duel I guess hit me once with a small spell to see where the absorb goes.

I have Nullbarrier, Resounding then Bullwark of Light from Avenger shield.

My understanding is DR first, then absorbs; but not sure on absorb order.

Also to calculate the DR, you’ll want to use the (1-DR) multiplicative approach.

So if your vers gives you 10% DR and a trinket gives you 15% DR and an ability give you 20% DR - you’d essentially go with (1-.1)(1-.15)(1-.2) = 0.9 * 0.85 * 0.8 = 0.612; meaning you’ll take 61.2% of damage.

So 1- 0.612 = 0.388; meaning you’d have 38.8%DR.

Very interesting thanks for this explanation that helps. Was trying to reduce the damage as much as I could before bubbles. Then stack Versa for bigger Bubbles kinda a 2 for 1. Since there are 3 bubbles now seems to make sense with all the other DRs.

Incoming Damage is always reduced by % damage reduction first. Multiple Sources are multiplicative as in the equation.
Damage then rolls vs Parry, Dodge.
Hit or miss. Then Block chance roll.
At this point is when it damages Health. Including any absorb effects.

As to what order. Testing time.
