Guardian's Gaze damage scaling

I’m not quite shure about this case. Two screenshots below the text, two links to the builds respectively. Why is the damage so different? Scaling? Bug? Something else?
Though, I’m almost sure, I’ve overlooked something important, but even checking all the info once more before creating this thread, I don’t see the reason for such a difference. Someone, please, open my eyes and let me see the truth :smiley:

(And yes, I checked, if it’s Darkblaze Source, but the conversion is not showed up on Devotion screen tooltips)

Chaos Blade Arc has ~2300% Chaos dmg

Acid Cabalist has ~2000% Acid dmg

Why the confusion? Look at total dmg modifiers. First build is chaos with no acid. Second one is acid with no chaos. Dmg values reflect just that. As for the weapon damage part (the 15%) the first build has a 2hander so ofc weapon damage is higher.

But why do I have only 2k flat Acid with 2000% and 4.2k flat Chaos with 2300%? That is what confuses me, not that I don’t have acid damage in chaos build and vice versa

Guardian’s Gaze has base 83 Acid and 193 base chaos at level 25. Hence why there’s such a difference in damage, chaos has more than double the flat damage Acid has.

Oops. As I said, I was kinda sure, that it was my oversight. Thank you!
