I'm starting to notice a trend in my major victories in Vicious dungeons: they all have happened during the time between rounds at debate. First was VHoS and DI victories to unlock the respective monster classes, with NC spread out over a particularly long tournament. Decided this weekend to try my hand at VGT with dragon shield+patches vampire, and though initial runs were torpedoed by RNG giving 8th or 9th floor bloodless, my most recent attempt had enough lifesteal, resists, and DR from a lucky platemail find that I was able to heal myself off of a berserking Horatio. Never needed any of the potions (Whupaz, reflex, and quicksilver included) that I had brought with me.
Yet despite this, VGT is now taunting me to try it without using a cheesy class like the vamp. If only it didn't take so much time, I'd be tempted to try throwing a fighter at it to see what happens.
