((base Gauntlet damage + Power Stat) x (Item Quality +1) x (Weapon Damage% + 1)) + Weapon Damage+) x (Elemental Damage% + 1) + Elemental Damage + = Total Weapon Damage.
Total Weapon Damage is then multiplied by everything else, like Gauntlet Hero Skill and Glasscannon for example.
for your Build, +200% Weapon Damage is added to the +50% damage for +250% Weapon Damage. in the Elemental Damage% space, you have no damage, so no extra damage there. if you had +100% Fire, it would look like this…
((BWD + Power Stat) x (IQ + 1) x (2.5 + 1)) x (1 + 1) =
((BWD + Power Stat) x (1.25 + 1) x 3.5)) x 2 =
(BWD + Power Stat) x 2.25 x 3.5 x 2 =
(BWD + Power Stat) x 15.75 =
with out the +100% Fire you are…
((BWD + Power Stat) x 7.875) x 8.25 (meteor does 750% weapon damage and gain 75% meteor damage from Aftermath Bonus) x 3 (+200% damage from meteor 40). meteor 40 drops three meteors. this is damage done before Glasscannon & Masochism.
I hope this helps and isn’t too confusing.
this is where I got the math from…
