In celebration of finally beating all viscous dungeons anyone who wants to should post how they beat various viscous dungeons.
Here's what I did (in order of completion)
Dragon Isles: monk trisword and taurog. Regen fought Matron.
Demonic Library: Cydstepping rogue with a lucky dodge to beat down avatar. After ripping his servants apart.
Namtar's Lair: Once again cydstepping rogue. Thank the lord I had first strike for last three forms
Naga City: Dwarf Thief with dragon shield. Trisword at lev 1, Humility at lev 2, Absolution at lev 8.
Used Agnostics collar to switch from GG --> Dracul --> MA --> GG --> Dracul. I haven't enjoyed killing any boss more than the Sun-Touched Sissy... It fells like retribution.
I speak chaos.
