So here's him:

I tried NM for kinda long but this character was the first one to even get past Urkis. How surprising it was to finish the game with 2 deaths only (still I don't qualify for NMRL

Well, oozemancers are well known for high survivability, so I there were MANY times I've survived when rare other stranger would. I've got the 50th lvl by killing the lich in Slime Tunnels. My first oozemancer (in somewhat 1.0x, still alive at 4x lvl) lost 2 lifes at the lich and couldn't get past him even on normal while this one did this well. For the High Peak itself, I used trace, then dug right to the stairs, killing minimum monsters (92+lvl, lol?). The final battle itself was a cake - healed twice the Aeryn with the nature's touch, used infusion of speed to close two portals (I might not have dont it cause battle finished in like 50 turns but still).
I'm very happy now! Maybe now I should try even further difficulty - INSANE
But earlier, the aims are the death room with dragons and atamathon, of course!
As always, I'm glad to read your feedback!
Have a good day, fellow adventurers!
UPD: dragons done without trouble, died twice at atamathon and I think I better go to the ID
