Done!
I almost blew it when I killed too many dolls at once in the Flayer Dungeon... life went down to 10% or so when I was about 200k exp away from L99.
I found an Ohm rune in the process, so I regard that as a special quest reward
(Edit) Her setup:
Enough in strength for a spirit monarch, rest in energy.
Maximum nova, static, energy shield, telekineses, lightning mastery, one in teleport, frozen armor, prereqs, rest in warmth (5 points).
Perfect Griffon's (except +defense) with perfect lightning facet (my PRECIOUS!), Crescent Moon, Spirit (just 33%, as she needs only 30% for the 105% breakpoint), Vipermagi with Um, Frostburn, Arachnid Mesh, rare boots with FRW and resists, Mara's, SoJ, BK ring, CtA+Spirit in the weapon switch, Annihilus, torch, lightning/fhr and lightning/life skiller, lightning sunder charm, enough lightning/life SCs to counter -res from the sunder charm, life/mana SCs.
She could wear more skillers, but I think that additional life/mana charms are better. Now that dying isn't much of an issue anymore, I could apply a more aggressive strategy, however.
