Black Robe has 5% on spell hit chance for three damage spell procs and Lifedrinker has 15% chance for a Blood Grasp proc. If Raze counts as a spell for this purpose, you will often trigger at least two or three of these four procs. A build with something like a sling mainhand, Lifedrinker offhand, and Black Robe armor could do crazy damage.
Yeah, I was noticing those artifacts on a recent Anorithil Insane winner. However, those trigger on spell hit, not spell crit. Not directly useful for Raze, alas.
Now, a build that's using Raze to trigger an enormous number of Corona procs might use those artifacts to ridiculous effect. (Can each of those effects trigger more than once in a turn? I have a vague recollection that I convinced myself at some point that spells procced from items have a once-per-turn limit.)
