Does anyone know exactly how this +X% is calculated?

It seems like the +X% is adding a lot to hammer damage. With concentration adding like ~370% bonus damage (50% effectiveness of 730% ~lvl 46), one would think that the +10% from a void is completely neglegible, but it is adding like 1k. Is this +X% to magic somehow adding the dmg to the base hammer damage before the % from conc is applied? It seems like it must be, or adding the total % to the total damage at the end (more or less the same as adding to the base before multipliers)

check on maxroll dot gg/d2/d2planner

but it doesnt show the equation, it just spits out the damage

I thought of a way to test that.
I'll come up with the idea later, i need to go to work pretty soon.

Physical Dmg : ((dmgbasex%dmgweapon)+dmgflat)x%dmgoffhand

Elemental Dmg: dmgskillx%dmgskill

Misread your question.

Is magic treated as elemental or special case? IDK good question

considering concentration is special cased to work specifically with hammers, i highly doubt the new mag dmg% stat sums with concentration's bonus. it would make sense to be multiplicative.

It definitely doesn't appear to be summing with conc. It's like a straight up 10% increase, which is true if big

+magic% dmg is added multiplicatively to hammer dmg

base * (1 + synergy total) * (1 + magic dmg bonus) * (1 + concentration bonus / 2)

Okay thats what i figured based on the output. Its just interesting the conc ED interacts completely differently from every other % increase damage in the game with respect to +% dmg items

Not only that, Concentration damage is processed additively when applies to attacks.
So it's even more exclusive to Blessed Hammer.
