Someone was complaining about part 5. I just did it on the first try, against Tower of Goo as my second boss (O.O).
Prepped Taurog, took all his stuff, had platemail preped (forgot to prep compression scroll), didn't buy anything from shops but a STR potion, took two DP's from Taurog to kill the bandit, converted over to JJ, converted all the glyphs and mana potiona I was saving for later, desecrated taurog, took Chaos Avatar after two hits on the goo. He went down to hitting + HP potions. I felt really dopey.
I did find the blood fountain at some point which gave me 5% sanguine, that might've halped (can't tell how much).
I'm honestly confused, I thought I should restart when I saw the goo. Very, very strange. Got Warmonge, DING! max and Unstoppable. Something wasn't right there, I don't think it should've been that easy.
The only things I can't account for in my calculations are the Blood Fountain, the Platemail and the 5% damage boosts off of Taurogs boons. Either it's the combination of the three or just one of them, but something gave me too much power (no shops apart from a potion and no glyphs and still steamrolled, whait what? O.O)
Taking a hint from dislexcia I used a goblin priest with platemail, went binlor (was a mistake, really), then found Drac, joined up not knowing lifesteal doesnt work, beat it on account of sanguine and goat subdungeon. and lots of bloodswells, and 2 schadenfraude. I made waaaay too many mistakes and suboptimall stuff to list. A carefull goblin priest of drac with platemail should be able to walk all over this.
I almost got pwned by Shifty Brickwork!
