Rage Question

I dont know how to transition to the question, so ill just get to the point

I deal 6k spin attacks without any kind of rage at all (6k earth damage, not counting thunder bcuz thats irrelevant)

But when i take off my armor and drop myself to around 300 hp (about 2% of my health) I deal 10k spin attacks.

I have 4 armor pieces with t6 rage so in theory i should have around +392-396% earth damage, but it looks as I have only around +40%

Idk if this is a bug or some nerf i havent heard about, but either way its weird (i also tested the exact same thing with melee but also got around +40% earth damage so idk)

 

This is because damage modifiers are additive, not multiplicative. F'or example the oversimplified formula for melee attacks with a full earth weapon would be:
base earth damage + base damage * melee damage % + base damage * earth damage %
not:
base damage * (1 + melee damage %) * (1 + earth damage %)
In the calculation the earth damage from rage is added on top of the earth damage % from your gear, so at it's normal that at full rage your spells don't actually deal 4x the damage as usual
Hope my explaination wasn't too confusing

 

Put your build in Wynndata, and then increase the earth damage meter manually by however much. This will give you accurate calculations.
