I only found 2 !str and 2 !wis all game, but I found lots and lots of !con.
That counts as lucky. Only 2 !con is utterly painful when it happens.
I found an upgraded Turmil [see other post about standarts changing] that made
a significant difference, though I would guess not too large a difference. I
found occasional weapons that were nearly as good that I dumped.
The gamechanger was a greater vault at 3100', I think the one called mirrored
quartet but maybe it was butterfly. I was able to clear about 6 of 8 chambers
or something like that. Whatever it was, you can play a few games without
seeing a comparable vault.
I got PB3 so late in the game I hardly used it. I could have played the full
game without it.
I almost missed the 300K turncount. It turns out M's detection radius does
not cover the entire level, and I wasted some time before I figured out he was
not coming for me. As the battle wore on, and time started running short, I
first started healing adjacent without phasing first, and even that wasn't
enough so I took bigger and bigger risks as time counted down. More luck
there.

I annotated with ':' whenever I picked up something notable, like a better
weapon or a stat potion or one of the greater wands/rods/staves. You can tell
wands from rods if I include [#charges] after the name.
