been farming sfk for magefist a while now with no boe blues drops yet
i have a 120 kill first boss to open gate
grab every mob from 2ed to 3rd boss
kill the mobs on top of the bridge
jump down kill a few more mobs below near the bridge and mass loot

heard someone say i got to clear room by room, which why im not getting any blues yet?
am i doing this right or missing something or is it just really low drop chance?

No. AFAIK It’s just RNG. I think the only thing that would hurt loot chances would be going too far away from your twink and being out of loot range.

Dang, I am so fortunate that I don't care to play priest or mage/lock.
