. . . when I find 2 rares in about 6 hours (RL time, not game time). Probably within 2 hours of game time.
Something called a "Harvest Reaper" which took about 30 minutes for me to kill (I was almost better off waiting for him to die of natural causes, since his head was on fire) dropped a Mana Conversion rare
Then, a Tukora Lieutenant (I am at 210 out of 250 for killing those buggers) dropped a Magic Resistance rare. I'm guessing that's a touch more valuable.
The long road out of poverty continues!
