After running with the Abyssal rune and Broodmother for weeks (no dragon soul) I managed to pick up the nevermeliting ice crystal:
The spell power is gravy but my question is, does the on use (20% crit) make this trinket a must have for shadow priests. Rolling a SW:P with 20% more crit throughout a long fight would seem like a beneficial. Add to that the base spell power increase and I wonder if its better than the broodmother or the rune.
Has anyone played around with this trinket yet? Thoughts?
