Just picked this game up recently - it's a lot of fun!
I just became hero #10 of Bay12. That's an amazing world - one almost wonders if the creator of the game slipped it in as an easteregg... probably not, but 3 vaults all up front like that? Talk about some powerful loot potential! I even managed to find the key in the dungeon right outside the starting castle... then accidentally wasted it by throwing it against the sealed door, which left a little key-shaped dent in the door, but didn't open it... luckily, I had some major +lockpick skill, so just picked the door.
Anyway, that's my second win ever, and first win with on the second difficulty.
I also tried the special level they have up on today's list - were you get the king as a companion right at the start. came || this close to winning at 200k with a force user on the third difficulty level (on my first try, even) which would've been quite the feat. Unfortunately, instead of shooting a force arrow at him, I didn't notice I still had my blessed sword equipped (to break his shields), so my character swung, missed, and was hit for lethal damage when the demon lord had - maybe - 5% health left, if that.
