As subject says, we have tested a difference against Kalli, when standing in the well of radiance, the radiant effect did not apply (using golden gun), which caps golden guns damage. EDIT: I do not mean damage stacking!! I simply mean because WoR doesn't increase ability damage, it's like you have no buff at all. This is changed simply by keeping the remaining buff for golden gun active. Really want this to be fixed before Lightfall releases!!
