Is the jolting touch dmg from Azureith's stiletto below the expected one? To be honest I am not sure of the exact mechanics, but it seems ridiculously high for a stiletto:

 

 

Just below you have for comparison the pierce crit dmg of the same weapon. Also please note that this is even stronger than above where I had only an enemy, if there were more enemies the damage will chain to them as well . If it's not a bug I believe it's kind of overpowered. For reference my 8th lvl barb has 23 might and the stiletto has been upgraded to exceptional quality.

Doesn't trigger very often. I'm guessing the spell has it's own accuracy setting or whatever. But it is pretty high, just not dependable. 

Empiric tests suggest that the triggering event is a critical hit.

Critical hit, once per encounter.  At least that's how it was on my last test.  Seems fine to me in terms of a unique property -- lets you deal one massive blow per encounter without consuming other resources, but offers no passive benefit beyond that.

Mid-game encounters are over pretty soon after it triggers... 

I've got this on a level 4 rogue right now & it is pretty crazy...did I just not notice how good it was on my last playthrough (Grieving Mother had it equipped for like, ever) or maybe it... got a stealth buff in 1.05? No seriously though, I probably just didn't notice.

I wish I knew how the damage scales. Adragan's Gaze, then Animancer's Boots jolting touch crit = 234 damage on Thaos.
