Glass Cannon passive clarification?

The glass cannon passive says you deal 6% increased damage but take 3% more damage.

This to me reads like ‘increased’ is additive and ‘more’ is multiplicative. Has anyone tested to see what these really are?

I don’t know if anyone has tested, but I believe all DR is multiplicative so if you had 50 DR on one item and one point int glass cannon, you’d take 48.5% reduced damage instead of 50% DR.

Pretty sure it is the multiplicative variant as it is ‘x 18% increased damage’ if it was just ‘18% increased damage’ it would be the additive variant.

everytime it say x it is multiplicative. If it say + its additive.

But there are some rare exceptions, like lh it says + but the math behind the +lh stat is different from other additive stats.
Effect Lucky Hit % * Skill Lucky Hit % * (1 + sum of increased lucky hit % from items/passives/paragons/etc.)

I thought it was the opposite skill % without any possibility to increase it and all modifiers on 2nd roll

Skill * effect (sum of modifiers)

well the numbers are correct, and tested by a lot of theorycrafters.
