So i got a Doombringer 925 and at first it showed 23k damage proc, then i noticed it dropped to 19k, then to 14k and now it’s at 12k. The same thing i noticed with some fixed damage aspects. I tried swapping some items around, thinking it scales with some of the stats but it doesn’t change.
Proc damage is based on the weapon you’re wielding at the time. Was one of the changes they implemented. So the more damage your weapon does, the more damage the proc will do essentially, this all depends of course, not everything is subject to this mind you.
That being said, no idea what is going on with your Doombringer. It could be a graphical glitch that takes into account whatever current buffs you have up? Not sure.
Post it in the bug forums, see if anyone else is having the same problem.
kinda hard to tell without knowing your build. however, a basic answer is that you dont always have your buffs from gear and skills up at all times. resulting in bigger damage ranges.
I generally look at my gear when i’m in town, so every time i saw different numbers was in town with no buffs, although even outside where i have the elements aspect cycle it doesn’t change the number on the item.
