Had an odd run today that almost made the leaderboard.
I found something like five or six rings, but could only identify one of them. Fortunately, that one was a ring of regeneration. I bet one of them was a ring of stealth, and had I had that at the end I might have had a shot again. I just didn't have the patience to test them all out, and it was really late (Troll territory) before I had a curselifter in my inventory that allowed me to see if any of them were cursed - none of them were.
I had a two handed sword (may have even found a total of three), but ZERO enchants. Also never found a scroll of monster confusion, a scroll of magic mapping, or a scroll of monster hold. I did have two scrolls of scare monster, and used those to advance in the later levels.
My armor situation was so frustrating. I found about 3 or 4 armor class 6s, but every time I encountered an Aquator it was in a hallway or in the dark and he got first move. I must have corroded about 8 different armors. Throughout the run my defense was atrocious and I took heaps of damage. I had my ring of regen to recover, but I had to burn my precious few charges of slow monster and polymorph due to a combo of low defense and relatively low attack power. Never did find waterproofing.
In the end I was dropped on Floor 24 (or 25?) right next to a dragon. I had nothing on hand I could beat him with. I tried to run but just ended up getting fried three consecutive times. Wish I could have saved one of those scrolls of scare monster - that would have been fun. And that was the point where had I had a ring of stealth it would have saved my life. I've found that on those late levels equipping the ring of stealth right before descending the stairs is a really good idea.
***Almost forgot - the most frustrating part of this run was how poor my... hit% (?) was. Against the tougher enemies I would miss over and over again. My experience level was about right and my strength was in the 15-17 range, so I don't know what the problem was.
