Not sure if I understand correctly. But the wepons looks a bit poo imho. Definatly the base DMG is not as good as my wepons currently, and no where near the sort of dmg of a prismatic.
The proc procs every hit I guess? so that would increase the dmg alot, but then it's only on draconic targets, so if your killing dragons etc then they would be well worth investing in, if not..wouldnt worry that much tbh.
Would rather have the right and left hand of Master Mcgillin from nek castle for the 300-400 dmg proc with 1.4 delay!
