Hmm. I haven't attempted vicious Halls of Steel since beating it with a Wizard shortly after Blahblah was added, so I'll have to give it a go once I get it unlocked on my latest new profile. A pure fireball strategy should probably thwomp Indomitable pretty effectively thanks to Mystera's new spread of boons, although I'm not sure if that will leave you in a position to take out Blahblah or not. Something to ponder, I suppose. I do have a general sense of 'WTF' from the decision to put Blahblah in that dungeon - yes, vicious Crypt was always more of a hard dungeon masquerading as vicious, but Halls of Steel was one of my favorite dungeons as it was just because it was so different from anything else. If it was too easy, IMO the solution would have been to bump Indomitable up to like 60 or even 75 death protections, or maybe do something like ~400 HP, ~25 death protections, fast regen and undead (for poison immunity). That would be an interesting challenge, while retaining the undiluted flavor of the dungeon.
