Warmonger is the (non-vicious) badge that I've earned for the least number of dungeons, even compared to purist. Not because it's necessarily always the most difficult, but because the lack of glyphs as leverage for killing monsters seems to make for very few powerful strategies and those eventually get dull. So far I only have two setups that I can reliably win with:
* The human monk carrying platemail and a compressed Really No Longer That Big Sword while worshipping Taurog. Buy whatever helps to get started, convert it all later for the inventory space to death protection spam against the boss if needs be, regen-hack everything to pieces in the meanwhile. Yawn.
* The orc berserker carrying dwarven gauntlets while worshipping the Glowing Guardian. Tank-hack magic users in dungeons where they happen to make easier targets. Don't actually convert health potions unless you need the extra piety for Cleansing physical-resistant bosses.
Any other viable combinations to liven up my badge collecting? One fairly ridiculous idea that occurs to me is to play an assassin, prep Earthmother for a single shot of Entanglement, then immediately boost my level with an Amulet of Yendor. Who needs glyphs when you can insta-gib 3/4 the dungeon! Now as to how that character would then actually fight a boss without poison ...
