I tried to rush it, and ended up not making it, but here's some of the run-up (I think there's 8 more runs for full rainbow without VGT and the 3rd tripple quest):

A quick Slime Pits PoSdown, usual stuff, at this point RL stuff has sort of piled up and I'm kind of just rushing it completely. Rainbowed it!
---

Same deal, except EM was on board. And you know if I'm packing Yendor I'm really just cleaning up.
Rainbowed this too!
---

He, he, he, just because I'm in a hurry doesn't mean I can't have some fun

I do enjoy DD, there's just too much of it to enjoy every run. And I haven't rushed all that much on this playthough at all, always found time for these

---

This one wasn't an actual pissorf thing, I just prepped binlor to open up the map and farm piety. Was quite manageable. Rainbow!
---

This, on the other hand was a "I wanna just win this, and win it quick!" thing. Rainbowed!
---

Then this took 2 tries, was expecting a better performance, but I suppose that's what happens when you're in a hurry.
---
Then I did a Human Wizard on Gaan'Telet, with pretty much the same preps as the Naga City Half Dragon, Dragonshield + Drac, was supposed to be a resist stacker with some nice glyph utility and big damage when he levels up. Worked really well, shame I clicked on continue before taking the screenie

---
Then I did this by mistake, because of the hurry - I thought I was missing a chemist here, but was in fact missing the rat

Was over quickly though:

and then I Ratcitified that mistake right away:

With a lightning-fast-cheeze-Rat. Binlor is actually quite strong on Ick, despite what it looks like. Pissorf's not a regen fighting strat and since it evades everythign Itsssamna just drops as collatera. You do have to move the other guy to him (or him to the other guy), but Pissorf kills plants cheaply and once you score the Endiswal you can farm plenty of Binlor Piety. I know it should be like that, but I've not really done it too many times so I was pleasantly surprised it worked (simply because it makes rushing through Ick a thing if you need to, otherwise blech, the damned thing works on Ick, too

).
---
And then I topped it off with a full-contact Chemist:

I was avoiding this place because it's not really too friendly towards either regen fighting or pissorffs, and I didn't get much out of my potions, but I did make great use of Byceps and Getindare to level up and then big health, resists, sanguine and byceps on a dwarf to kick the druids ass.
---
Right, so, after all my miscalculations, 8 more runs to go - 2 rats, 2 chemists, and one thing in each of these - Dragon Isles, Demonic Library, Naga City and Gaan'Telet. Then I just do wiki work and slowly peel off VGT whenever I have some time and take out the last tripple quest. But as far as research and this particular playthrough goes, full non-VGT rainbows is what I'm satisfied with, RL stuff caught up with me.
It's funny because what happened on every other playthrough (quite a few of them) was that I made the mistake of "doing just one VGT run", and then got caught up with it, it took too much RL time and I both burned out before rainbowing all the vicious things and also caught myself spending too much time on DD (and the ocasinal bug storm crashing VGT runs also wasn't good for my mental health). This time around I said - right, VGT's my trademark dungeon, but I'm not gonna fall into that trap again, and I went and did do everything else with all sorts of stuff (and copious ammounts of pissorf spam this time around but I did do a ton of wacky PQI and got quite a bit of research done and my backlog of things to try out in DD has shrunk considerably ^^ And I did avoid Binlor like the plague on the previous 2 playthroughs, and the crystal ball on the previous one, so this time the PQI and conscious decision had me avoid Gnomes and Mystera respectively as I overdid them last time around more than Tinker has

).
I also avoided Orcs like the plague, and tried to only do PQI ones and spellcasters (if it overlapped), and I also avoided TT potions like the plague to not fall into a habit of just lvl1 bosskilling stuff (also avoided the Fabulous Treasure), just about didn't touch the guitar, did my best to play mazy maps with no wall removal help...
This must've been the strangest and most atypical playthrough I've ever done, now that I think about it. Most of it was the dregs of my PQI - including most of the Orc spellcasters, which also helps explain why I'm so hugely annoyed when Tinker tries to read my personality or playstyle preferrences from it. Even the stuff I spammed like mad was stuff I avoided for years and years, maybe one or two monks were Human or Orc, every thief was a Goblin when it wasn't a Dwarf, I played more elves than ever (and not a single one with Codex), I played a bajoilion PQI halflings, I actually prepped Elite Items (both as a prep and as in actually prepped elite stuff out of a locker, which I always avoided doing for various reasons), played huge swaths of runs purist, took out the VT's in most places first thing, played more dwarves than in all the playthoroughs combined, probably didn't play a single Gnome Bloodmage, used JJ a lot, struggled with Vampires... If someone told me a few years ago I'd ever put in such a playthought I'd have a hard time believing it, but there you have it, a Bizzaro Lujo playthrough. It was like as if Darvin did an all-potions spiker playthourgh, or if Tinker modded fireball out of the game

I played Halfling Warlords to great sucess! And took the Dwarf Warlord through all the Vicious Dungeons! And did mad stuff with Goblin Rogues! And pissorffed Slime Pits with Elf Berserkers! And used Cauldron with Gnome Transmuters ^^ Wheee!
Not over just yet, but it was quite a ride, and I'm rather pleased with how all the stuff I haven't been playing that much works nicely when you find reasons to give it a shot. A few things I'm really miserable about not spotting during beta as they're just begging to be tweaked/modded/whatevered, but way less frustration than on any other playthrough before (well, there's a few reasons for that I'm keeping to myself, though).
