Ideally this thread will be replaced by a full-fledged wiki at some point, but so much changes in early beta...I'll get us started.
12 Classes: 3 each at the Guild, Thief Den, Church and Mage Tower.
7 Races: Humans, Elves, Dwarves, Halflings, Gnomes, Orcs, Goblins.
7 "extra" buildings: Tavern, Explorers' Guild, Bank, Taxidermist, Blacksmith, Bazaar, Witch Hut
5 Gods: Dracul, Glowing Guardian, Mystera Annur, Taurog, Tikki Tooki
16 normal, hard or vicious Dungeons: 2 in middle, 3 each in South, West and North, 5 in the East.
Several items unlocked in the stores by completing each easy dungeon.
SOLVED Now for some crowd participation... a post in the bug thread suggested that you can find bludtopowa with a berserker. Either I haven't unlocked that ability somehow, I'm bugged, or he is doing some weird stuff. Someone let me know which of those it is? -They don't pop up in the central dungeons (as often?) Thanks, guys!
