I cleared Blood Furnace at 64x5 yesterday with ease. The last wave of the 4 waves was kind of close for 1 of my shamans, though. But I could have used ankh if he would have died. Last boss was piss easy, even without an elemental. Grounding: nuke the casters 1 by 1 and renew grounding. And the boss drops so fast that you can get him down before he does his AOE.

Can't wait to hit 66 though. I'm pretty tired of grinding BF/Ramps and I'd really like to be able to completely clear Slave Pens and Underbog for some variation (and Mana Tombs/Durnholde Keep if those are do-able at 66).
