So far, this weapon is very mysterious... there are many obscure in game references to it, moreso than the other legendary weapons, to my knowledge...
-The prince in DM, which you mentioned.
-Caretaker alen outside of LHC mentions it.
-It's mentioned in a grey fishing book that drops in AV.
-A gm equipped it on test server at some point and it was linked to allakhazam, so we know the stats of the weapon, but not the proc rate.
Due to this being a higher tier weapon than thunderfury, and presumably much harder to obtain (possibly requiring far more than just defeating nefarion for a questline or something), and that it has no stats other than the proc, i'm personally guessing that the proc rate is pretty high... like say 20% or higher. But, what if it procs at a 30% clip, a la thunderfury... it IS called ashbringer, so i'm guessing whoever you fight will be ashes in a hurry
Needless to say, I wants it
