Gathering Storm Tempest Weapon

Does anyone know if this node applies to both weapons if you’re dual wielding? “Gathering Storm deals additional spell damage per 3 melee damage on your equipped axe or mace.” I’m assuming the “or” is just specifying that only those 2 weapons apply not that you can’t do both or 2 axes. Just trying to decide if I should use a scepter main hand and an axe in the off hand or dual wield axes.

I’ve been wondering this as well. I think I’m sorta locked into using two axes either way, but I want to make sure to know which one to put in my main-hand vs off-hand if it’ll only take one or the other. Or if it bugs out and won’t take either if I’m dual-wielding them.

It benefits from both axes.

Its really hard to tell since we dont have a visual damage metric in game. I didnt notice a difference using 2 1h axes
