On the dummytarget it looks like that Disintegrating Aura (DoT) gets Double Damage (Hit) procs from the Hammer Throw skilltree.
I believe this is working as intended - the double damage nodes don’t explicitly mention “hit” anywhere. If people think this is un-intuitive or overpowered we can certainly look into it.
Thanks!
"Zealoth’s Conviction
Hammer Throw hits have a chance to deal double damage."
Also, it states Hammer Throw and not Disintegrating Aura which is a skill by itself (underlined)?!
“Disintegrating Aura scales with […] but not with other nodes in this tree unless specifically stated otherwise”
so sort of 2 bugs in 1.
