So I’m just wondering about gear, how do they stack with each other? All I’ve heard is that skill damage stacks multiplicatively. I take it that that’s how it’s handled globally as well, but I ask just to make sure.

More specifically, there are three things I’d like to know;

- How gear and helix choices stack with each other.
- How different gear stats affecting the same thing stacks with each other.
- How gear stats
*within*one piece of gear stacks with itself.

So to kill two birds with one stone right off the bat, looking at 1 and 2, I’ll try and use the following example of what my question is about.

I’m Alani with these two pieces of gear in my loadout;

At level 5, I choose the mutation which increases a triple stack heal by 25%.

So how does it add up?

(X is the base healing amount from a triple stack at level 5)

Purely Multiplicative

X*1.014*1.091*1.25

Purely Additive

X*(1+0.14+0.091+0.25)

Multiplicative gear, add helix

X*(1.014*1.091+0.25)

Additive gear, multiply helix

X*(1+0.14+0.091)*1.25

Multiplicative on same stats, add differing stats affecting the values (didn’t know how to put this, basically multiplying the healing buffs and adding the skill damage on top of that in this case)

X*(1,014*1,25+0,091)

Additive on same stats, multiply differing stats affecting the values

X*(1+0.14+0.25)*1.091

Or maybe another possibility which I may have missed.

Moving on to 3.

If I have Solar Sustainer on Miko, will the secondary effect be additive or multiplicative to the 2nd value, and how will it interact with the main stat with his healing beam? I.e;

(Y is the base healing of healing beam)

Purely Multiplicative

Y*1.14*1.0546^2

Purely Additive

Y*(1+0.14+0.0546*2)

Multiplicative across stats, adding within

Y*(1.14*(1+0.0546*2))

And once again, something I might be missing here.

As you can tell, I’m not exactly a math virtuoso
