On damage formula...

[Delmuir]

How does damage from directed from "on hit" or whatnot from armor, etc., affect total damage?

Is it just added on at the end (which makes the most sense) or is it affected by multipliers, etc?

I ask only because I'm playing a Ghoul Cursed using the Blighted Maul and I'm doing just ridiculous amounts of damage… usually around 900 or so per turn. I was using gear armor that had few bonuses but about 40 damage on striking. I switched it out for the seemingly vastly superior Blackened plate and my damage dropped almost in half. WTF?

I just can't seem to figure out how the final damage output is calculated.

It is affected by multipliers and stuff.
