First of all ... not genociding mind flayers was a big mistake. I got brainsucked so many times, even with a greased helmet. It's embarrassing. Next character will kill them all first thing.
I got Mjolnir early through prayer, and not much later Grayswandir through prayer as well, sticking with it most of the way. Got crowned by Tyr - a first for me. Still can't keep a pet to save my life. I have, at least, finally mastered holy water, and I was totally stocked the whole game. Found a stack of other artifacts along the way, but never wished for one.
Come to think of it most of this game was pretty uneventful until the end. I plowed through the Elemental Planes without any problems; twice the portal was within 12-15 squares of my character. (sweeet) I picked the center altar on the Astral Plane (correctly) but lost about 25% of my hard-drunk HP to Death. Ran out of confusion-inducing items otherwise I would have tried the pet trick again like I did with my Caveman.
The tale of the tape, then!
Chihiro, lvl 30 Valkyrie, the Hand of Elbereth, 295 HP, -23 AC, wielding +6 Grayswandir
Eight artifacts, zero gold (I gave up on carrying it all), 153 gems and 24 amulets
(better than gold, I figured)
Never changed form
Killed Baalzebub, Orcus, Yeenoghu, and Juiblex, but bribed Asmodeus
one measly arch-lich before genociding them (along with master liches and disenchanters)
and I didn't freakin' extinct anything, but did kill 119 soliders (?)
I want to do the Wizard next, but I need to master keeping a non-combat character alive first :D
