Well, UberVlad has been through 4/5 of NM with only a few glitches, most
notably in act IV.  An OK killed him once.  I was amazed at how he was
able to deal with them most of the time, thanks to my Grief and Exile,
courtesy of Mickey.  Some highlights:

I never saw Izual die so fast.  I just Zealed him and he was down almost
immediately.  Usually my mouse finger gets tired whacking at him.  But
not this time.

Hephasto killed me when he died.  I guess my life was just a tad low to
survive.  Got a Hel rune out of the Hellforge.

I accidentally broke a seal in the Chaos Sanctuary and had to deal with
Infector of Souls and his minions while dealing with all the monsters
(including three or four OKs) at the same time.  I used one fat purple.

Diablo was ridiculously easy.  Three or four whack with Smite and he was
gone.  I think he hit me once, maybe twice.  I couldn't quite tell
because he went down so fast.

After that, it's off to Harrogath to take on those guys.  Somehow I
don't think I'm going to have much trouble with Baal.  I also need to
gain three more levels to use the Fortitude armor I have set aside.

Thanks again, Mickey!
