Dungeons and strategy

[ScrawnyRat]

Just two quick questions.

1. How does one get the first dungeon key? Does it just drop in a random quest, or is there something else you have to do once you hit level 10?
2. I've not noticed any direct benefits to the character for levelling up in terms of stats (outside the level award and the cash gain from working). Is there a better way of questing than simply taking the one that provides the most gold:time? Or does the gold gained from work balance this?

1. Key appears at random quests after level 10
2. Imho the best is to choose best exp/time quests, becuase with higher levels you gain more gold per quest and more gold from city guard. And the most important you gain access to higher dungeons and better items.

Exp/time is indeed the best way but sometimes I also go on gold quests if I desperately need money to buy potions (with only 1-2 hours to go before I go to bed).

Though my best friend's sister got the key at level 7 on a quest. She is now level 19 and she has the second dungeon key. Is this normal?
