First I started by getting the SMC blanket. Then to herb farming, along the way I found a pool which gave me a wish, I got wands of destruction, got literacy and found really nice mithril warhammer of penetration and crystal tower shield. Was crowned around 4k, got =Fire and Deaths Blade, the latter is the suckiest gift though. Also killed a cat accidentally with acid spit, didn't look properly through all the mobs. I was maybe lvl 10 when finished here.
Next was getting tele wand (scroll of item detection from Waldenbrooks)dwarven graveyard, darkforge (paralyzation resistance, tele control and teleportitis from pools, really good even when stats were drained and got cursed), and pyramid in that order. Got eternium 2-hander from DF, which was better than the Deaths blade. For the rest of the game I used either the eternium 2-hander or penetrating hammer and shield. Levels were about 11 when entering DF and 15 when getting out.
Then tower, top level had room of shadow wyrms, and one dropped Preserver(!). Smashed the ACW with my hammer though it gave me mana battery, got out, and took the corpse to druid, and drank the potion. Those shadow wyrms would've been quite deadly elsewhere with their cold breath, but the tower negated that. Actually most promising PC before this died to a combination of ancient white dragons and earth temple on same level (because drakeling heat).
Then the final dive began. In Dwarftown I visit mystic, get scrolls. DH2 had a big room of ghosts which were tricky, but with a little use of wand of digging and teleportation I found the stairs and got through that way. Water temple, graveyard, banshee were all really basic, and notihng remarkable elsewhere either. Then EG, I spit at him and teleport on the stairs. Casino had some goodi stuff, ring of invisibility was the most notable. Then I zap the shopkeeper and teleport away.
Cat lord was hostile, he appeared near the upstairs so I make him follow me up, away from the stairs, then teleport myself down. Didn't want to fight him with no slaying weapon. Air temple goes easily, invisibility makes the day. Yulgash goes down in two blows. Earth temple is a bit more trickier, but my hammer is the best weapon there is against them. Here though acid trap destroys 2 SoCR and all my booze, not good at all.
Then mana temple, easy. Kill the mobs, and soon the main man comes out. He dies by the sword. I remember being lvl 23 before killing him, 25 after that. Also an artifact guardian on UL6, really tough ancient minotaur. Dealt over 200 damage in single turn with 3 criticals through DV70. He dies, I get wyrmlance. Also kill a balor at some point, one of the few random high xp monsters.
Then down to the final battle, which was quite tight and eventful. It was one of the most interesting ADOM fights I've had, others include an earlier D50 speedrun fight... but I lost that one. I try and explain it in a bit more detail.
D49 goes nicely, this time I had heavy crossbow and bolts to minimize time in the cold. It doesn't drop down but by maybe 80 (100 is the maximum), to around 50. 2 wands of fire warm me up to around 70 speed. I start by frontal assault, killing the mutants, servants and masses. I don't wipe them all out, but teleport to the lower corridor entrance. Then I proceed to clear the corridor, and a servant drops Nature's Companion - really good. When I've reached the lever chamber and cleared it out partially I teleport near the lever, avoid the balor and destroy it. Then to the upper one. I teleport to the corridor entrance, and there are now some remnants of the mobs and also balors in the chamber where the corridors start. I try and make it to the corridor as fast as I can, to fight only 2 opponents at a time and kill one balor who came from the room side, and while slowed too - nice xp. Then in the turning of the corridor, a balor teleports into the empty corner. I kill it. Around this place I get SLB. I try to teleport to the lever chamber, as the other balors start teleporting into the corridor though there's other mobs between them and myself. Alas, I don't find an empty spot in the room and get teleported out into the right side of level. With only one charge at tele wand (and random teleportation) I create traps to get back near the lever. I eventually make it back to corridor, but am stranded between monsters I can't kill lest I get in touch with balors. This time I am nearer to chamber though. I start zapping wand of wonder, and happy days, I get teleport. I bless and drink 2 potions of boost perception to get a good look at lever chamber. I teleport in to the empty place nearest to lever I can see. A balor is next to me as I bash my way to the lever. I eventually make it, destroy the lever and use my last teleport to get to the stairs. I am extremely corrupted now, but alive and succesful.
Then I make my way up, don't kill the cat lord, just pass by it, and come through the DF shortcut. You can use that to go up, even when you don't have ring. I hear there's some noble creature that could rid me of my corruption, but I don't want to waste time chasing rumors. I want to get home.
But sadly my life ends in loneliness and isolation. But at least Ancardia is saved, and quick, that counts for something, right?
EDIT: I'll add some more turns counters which I remember. Tower was finished soon after 8000 turns, and I was in earth temple around turn 14000-something.
