Just used that to grab a third win (Troll Heart, Binlor->Dracul on the surface, mass buying stuff then TT->Dracul for the bosses) - gorgontime : ) cautionary points for posterity:
1) Do not trust the +% damage from anything at all ever. The number of enemies I thought I'd kill with Stone Fist was much much higher than the number I did kill.
2) The pactmaker piety sinks are not great options on this level. +max health is nice, but it will kill your piety gain and boons, +% resistance is also nice, but you really want to avoid getting hit with the enemy loadout, +xp is obviously a little silly
3) Tikki Tooki punishments got me twice... watch out for them
4) Desecrating altars provides diminishing piety returns.
Somewhat disappointed that the Gorgon's conversion points are *completely* pointless against bosses - I mean, there's no other race which has their cp advantage completely negated for the bosses. Otherwise very fun. Still, managed a purist havendale bridge run with every last tiniest resource used up (Mystera->Taurog->Binlor->Taurog is a strange conversion pattern).
Also, as a budding half-dragon user, has anyone beaten the matron with one - I haven't given it a shot yet but it looks very rough - 50% MR, no walls, no other enemies. I guess piercing wand/fireball/Dracul or something if you can make up the attack somewhere.
