Had this staff since level 52. I'm at level 65 now and I have yet to replace it. A few have come close, but the +43% damage to stunned enemies as a lightning sorc is really quite incredible. I've upgraded it three (out of 5) times now -- Even Unique Sacred items haven't come close.
Was this just a super lucky drop?
I used to not care about perfect rolls, but now it's been ingrained to only search for those. (Or where most are perfect). I'm level 69 (nice) now, and am literally selling/salvaging anything that's not ancestral perfect/near-perfect ๐. Maybe I need to drop my standards a bit.
