Ok, done it - big props q3. I had 2 failed runs and then the game just showered me with optimums.
I went with Fabulous Treasure + Transmutation for the 100 gold to righteusly buy out the shops for CP, patches for the crusader-like loophole, extra glyph for options/net CP gain if I keep any glyphs, quest items for a chance at running into all the cheeze/good CP fodder, salve for the statue, fortitude for the dragonguard, dodge and reflex for the lol lvling and whoopaz for the boss.
(Now to give the rest of the megapro society a heartattack

)
And then rng decided I was it's most beloved disciple as I ran into: HALPMEH, Platemail, Martyr Wraps, Whrgarble, 2 lvl 7 Zombies (+ 2 lvl 5 goo blobs) and a, wait for it - Pactmaker + Sensation stone first floor. I mopped the floor like it was Hobblers'. I even ran out of gold by accident and the only thing that was left in the shops were the Martyr Wraps, which is akin to forgeting to bring your genitals to a Croatian wedding... And didn't even start on the bloodpools or potions, so I gues that vamp could've killed a heap of horatios piled on top of each other

As far as luckouts go, I'd rate this at "debug mode level"

Only thing missing was GETINDARE to shave off, oh, several thousands of damage throughout the level... I feel incredibly ashamed, yet cant stop smirking stupidly...
EDIT: Since I don't think the Vamp will be fiddled with, and the sillyness only works here, that 9999 gold is totaly up for grabs if you know your lifesteal antics...
