Thank's a lot for all your advice !!
As you probably mentioned, I had not much time to play in the last days...
But today I'm going to finish Skull Castle.
I will ignore the lvl. 12 Lock and go back to the city for my Exp. and new Quests.
By the way: I love this forum ! It is alway interesting to see what questions the other gamers have and if someone answered "your" questions

See you later
