Got it!
This is, obviously, NC purist. Had a first strike glyph, had both wonnafyt and wheeytwut upstairs, had crystal ball, fire heart and battlemage ring, tons of money, cheaper items, the ability to take more junk downstairs due to compression seals and so on and so forth. One subdungeons was... idk, the bonus one was gold.
Gods were - mystera for mystic balance and one hit of magic (had the +2 amulet on me, took me to 20 mana), and also 1 or two hits of weakening I think which helped with the goblin and iron man, then at some point EM for patented "how to get clearances in NC underground several times", then I was trying to be clever and got ported back to the entrance behind a plant (on top of it first) so i took consensus and killed the plant, then took the remaining clearance and completely without potions or options (I think), I went gg for protections. I desecrated Binlor and then later EM.
Yes, I technically went in prepped (seals) and found the exact junk I was looking for in the shops (no, really, crystal ball and fire heart - that's what I was looking for - would've settled for witchalok pendant, too). It's probably possible to do it in other ways but I woudn't know what to tell you about that. This was first try with tinker, had 3-4 longish fails with various assassin before that. It was tense, close, and I almost got myself screwed over by accident (and bug?).
