Ok, i decided to scrape the long rant before people get corroded, in favour of a more lighter note:
I just had Horatio down to 2100 health with the gorgon. It was a massive luckout, though, but at least there is a way to luck out with the gorgon - which is good news. Key thing is HALPMEH, which I simply didn't chance into before.
Typing it up now, but still, if you're doing gorgon I feel bad for you son, it took 99 trickshots and I still haven't won.
So preps were - Binlor, RBS, Subdungeon, Extra attack, Dragonshield, Compression Seal, Fortitude, Burn Salve, ??? and Whoopaz.
Luckout was - HALPMEH, Gloves of Midas (had to scrape them though) and Platemail. Spent most of the game with those things and it worked. Also used fireball, and later BYCEPS. If I had money, there were martyr wraps, and a tower shield in the shops but it was impossible to get them (I think).
Floor luckout was - I managed to kill the illusion with only 3 weakenings stuck on me, but drac and the statue showed up at the last possible moment, with only two floors to go in an impossibly perfect and perilous moment. If I didn't find both right there and then I would've lost. This also means I got to floor 8 on only Binlor, and managed to get my magic resists maxed out in the process. Also, first floor troll, second floor fully explored, third floor revealed and a late Drac + luckout ment that I had a bunch of bloodpools lying around.
Bad Luck was - No IMAWAL, so no knockback ws. Horratio, and no soul orb which might've affected my gameplay. In an impossible stroke of luck, I've seen the least ammount of wraiths I've ever seen in a VGT run. I still reached horatio with 0 potions. Reason I didn't have money is that I HAD to buy a keg of health and use the potions to spike someone (can't remember), it was that bad.
Gameplay was - play TIGHT. Like, q3 with a savegame playing PBEM tight. Use endiswall at every opportunity, prioritizing subdungeon/lowe floor/piety walls and setting knocbacks up. Binlor up your resists slowly, but save exploration at every corner, and time stoneskins to not coincide from the might on wall destruction, if possible, or squeeze the deathgaze wins where you otherwise wouldn't. Also, using binlor to free up your bloodpools might be a good idea.
Key - Halpmeh. It's pretty much impossible any other way, and tbh it's also impossible without Drac, and those two only really work togather for the paladin. If you can get your resists from Binlor and whatever other source (you need 18%-ish), I think you can just grab sanguine and get out, but there are several ways it can play out. Halpmeh + Rbs+ Resists beat everythign but mana burn, that is, don't fail horribly against anything, except a long stretch in Drac is suicide. Hurrying your binlor development for an early 100 piety dip into Drac for the shield and sanguine, then going back into Binlor for magic resists and unrestriced halpmeh shennanigans might be good, but god knows how difficult it would be to pull off...
Pro tip - luck out massively. Like, hugely. Get everything possible lined up and play to the best of your abilities, and it could be doable. Maybe. Also, god knows what I'm missing, ofc. I've made mistakes, but I was juggling to many plates for my skill level. IMAWAL monkeying at Horratio can't be done in binlor, and Halpmeh can't be done in Drac, so finding the optimal way to juggle those two could be key to figuring out.
Good news - Binlor might actually be good for stuff in there. Well, poison strike was big and only Gorgon can have it reliably, but a rather effortless max magic resists is nothing to sneeze at, plus "free" mights on wall destruction. Might be a hoot with Monks.
