Volatile Reversal - Increased Damage Taken and Increased DoT Taken

[ClownCombat]

Hello,

The Skill Volatile Reversal can apply two debuffs via the Nodes:
Harbinger of Dust and Time Rifts

I know that these Effects can stack individually (which might be impossible with CD nerfs), if one hits an enemy with both void rifts.

But do they stack additively or multiplicatively together?

So, If I deal 100 DoT to an enemy hit by one of the void rifts, does this enemy take:
A: 100 * 1,3 * 1,6 Damage
or
B: 100 * 1,9 ?

[Heavy]

All effects that are “enemy take x% increased damage” stack additively together.

So

@ClownCombat

B: 100 * 1,9

Is correct

They are only multiplicative with negative resistance and armour (through resistance shred/pen or armour shred).

Thank you for the fast answer! This helps me a lot
