Eh, there's very little talk of the sorcerer at all. There was a thread about viable VT run classess, and Avatar mentioned that he's herd good stuff about the sorcerer (namely the goblin sorcerer).
B2P is really good with sorcerers, and it's helped me do trickier sorcerer VT runs. If anyone's interested, here's my non-vicious routine.
Sorcerer, mystera, goblin, subdungeon + whatever. Crystal ball is good. If you want ease you can take magnet fireball but you lose a bit of efficency with your conversions. Then you play it like a straight up spellcaster, spam whatever untill you find fireball (or fireball) for mystera piety, get what you need from mystera (everything is good). B2P is a great find because stuff hits hard and health is wasted anyway. Unload with huge mana pool + mystic balance + refreshment + goblin level ups + crystal ball (you're practicaly an elf anyway).
It worked almost everywhere sub-vicious, but it doesn't work everywhere because mystera doesn't work in a few places due to specific hickups. However it's a very powerful and very reductive system, and I've been amazed time and time again at how powerful that 15 mana at start actually is and how easily it allows you to play a straight up spellcaster.
