Halfling Monk of Taurog works as well. Bring a Really Big Sword and a Compression Seal (but don't use the seal on the RBS, because you'll want to ditch that thing eventually). Dragonshield or Dwarven Gauntlets as your locker item, and don't forget Extra Attack. Since you're converting all your glyphs, you get a pile of potions, and you can engineer high level kills that even the orc can't manage. RBS and Taurog mean that you don't need to fear Tower of Goo, Tormented One, or Bleaty, who are the usual showstoppers for Warmonger runs. Firstborn is still a problem, but with Taurog's Helm, 12-ish health potions and a bunch of death protections, I'm sure you'll figure something out.
Patches is very good for this run if you can stand the loss of Bet on Boss. Manaburn doesn't matter to you, and poison is easily dismissed when you're a conversion-happy halfling. If you get even one dose of resistance from Patches, then it was worth it. A +4% bonus when you're already at 65% is roughly a 10% reduction in actual damage, which is pretty great.
