Thanks for the advice. I had tried with the berserker (since non-Vicious DI with a berserker was the first Vicious dungeon I ever finished) but couldn't manage my curses.
As for using glyphs, the tricks I am aware of are:
* ENDISWAL or a Transmutation Seal to crack the wall at the entrance of the final lair. This bypasses two. I usually prep Transmutation Seal because it feels pretty hopeless if this doesn't happen.
* PISORF knocks the last guard out of the way (and you can use it on the boss too), as does any knockback. Or, now that I'm thinking of it, the Taurog prep.

* LEMMISI plus WEYTWUT can skip them all, if you don't mind being cut off from the rest of the dungeon and praying that WEYTWUT breaks that 50% magic resist.
Are there any I'm missing? Typically I've done Transmutation + a Slayer Wand + maybe knockback the last guard. Everything seems good on paper except that dealing with even one 50% PR, cursing Dragon Elite with Taurog-diminished mana sounds horrifying.
