Does damage boost stack?

If so, is it additive (100% + 50% + 50% = 200%) or multiplicative (1.5 x 1.5 = 2.25)?

I think most do and one or other combination don’t work. Don’t quote me tho.
Also I don’t know the math behind it.

Damage amps do stack and I THINK its additive

all damage amps stack, and it’s additive. 100% + 50% + 50% = 200%.

discord is special. it’s considered defensive debuff instead of offensive buff, so it alone is multiplicative.

The only answers I can really find are from 2017

Here’s a video of a guy testing it (Back when Mercy had mass rez, so it’s old)

What if this could work, nano + Otis’s ult + mercy staff + amp matrix + discord. What would that math be.

All are additive with the exception of Zenyatta’s Orb of Discord, which is multiplicative.

Mercy: +30%
Orisa: +50%
Ana: +50%
Baptiste: +100%
Zenyatta: x1.25

Zenyatta’s boost is multiplied after all others.

So basically, you get 200% from all the ults
230% boost when you add Mercy Staff in
THEN multiply THAT by 125% from discord
We take a Scoped Widowmaker shot
120 damage,
After boosts it reaches 330% damage, which is 396
Then discord bumps that up to 495
THEN it can headshot which totals up to 1,237.5
Just enough to take down a B.O.B in one shot

Edit : Discord only debuffs by 25&

You are to smart for me.

(100%+50%+50%+30%+100%)*1.25 = 412.5% damage output

Does Orisa fortify and Ana nano damage resistance stack, both of which are 50% adding up to 100% damage resistance :thinking:

Nope, Damage resist stacking happened exactly ONCE with Bastion

It was Hotfixed with a Napalm Spewing Flamethrower.

Boost is additive and debuff (like discord) is multiplicative.

ok but guys, someone needs to test a combination of:
Mercy amp
Nano Boost
Supercharger
Amp Matrix
Discord

i gotta know how much this would do

I already did the math.

Just add everything but discord together and then multiply it by 125%.

It does 412.5% damage.

oh, well can anyone show a visual of it as well?

I’m not sure what you want a visual for. Can’t you just imagine it?

That but the B.O.B is instead shredded into scrap as his very existence ceases.
