Roughly, haven't played in a while because of the huge difficulty wall of Vicious dungeons; decided to come back to the game, remembered I still liked it, would like to actually get good enough to make some more progress.
Context:
I've finished HGT purist, but zero vicious dungeons.
Most common race/class combos are Elf Assassin and Elf Tinker.
Terrible at: Potion races, potion management, conversion, gods (that's probably the big one - my first run since coming back (not counting "showing a friend who'd only played alpha Vicious Steel" [which I resigned after finding the bosses] was Elf Assassin in Hexx Ruins, which I won Faithless despite the fact that was not my intent going in - it was actually to get the 'buy all shop items' quest, which I failed.)
Typical preps (for an elf assassin): Elf boots, bet on boss or black market (depending on whether or not I think I'll win), apothecary, more mana, compression seal, perseverence badge, no god, [mana, schadenfreude, reflex, quicksilver] potions.
Not really sure what other information might be useful - feel free to ask.

(† importing undeath to Desktop Dungeons has proven nontrivial, due to something called 'vicious dungeons')
