Post silly PQI results. :p
I mean...Orc or Dwarf, mmmmaybe. Any other badge, mmmmaybe. Goblin Rogue Warmonger + Rex? Maybe back when Rex was a wuss. Dealing with 95% Berserk to I think it' 128 damage on a Rogues' hp pool? At best I could prep TT, get to 30% dodge, maybe 3 Reflex/Quicksilver potions + 1 each prepped if I go in with Yendor, start at L5, and rack up piety. Even then, all those 50% dodges need to work, because I can't survive a single hit from Enraged Rex. Even then I'm not sure five hits w/out Dwarven Gauntlets prepped would be enough to nail him.
Mind you, this also means no ENDISWAL or PISORF to keep Rex from cornering me, and I'd need to convert to GG, JJ, or EM to get enough HP to take even one hit from non-Enraged Rex for the Bear Mace to matter. I'm welcome to advice on this one. I'll probably just do the much easier flaming Havendale Bridge, and I'm sure there's some way this PQI is "possible", if not very likely. I'd be interested if it can get done for less than the 500g reward. I am pretty sure Yendor or Dwarven Gauntlets has to be prepped.
