Void Knight - Hammer Throw - Disintegrate Aura

I work on Hammer Throw with Disintegrate Aura. It scale with increases void damage , damage over time and throwing attack damage.
Since there is no tooltip for aura damage, it is difficult to figure out which affixes have the most impact.
Does anyone have experience or tested how it works?

They are all equivalent, 1% increased void damage = 1% increased damage over time = 1% increased throwing attack damage.
