Okay here's a tipp;
Never ever bother yourself with grinding monsters,
except if your're farming for money or items.
But for gaining xp its useless.
Second;
Quests does give often fine items and skills,
you dont need todo them but you will receive
benefits like free skills, either you have to buy them.
Third;
On the Ascalon backyard is a portal, walk thru
to get to your first mission, it will be a shield shape on the map. If you done them you will get to another mission which you can do, you also can walk by yourself to other cities but that supposes a high level due highlevel monsters blocking your ways.
As you can see, behinde Ascalon is a shield with two swords, walk to it and finish it.
The swords indicate what you've done, one sword says that you've done the mission target,
two means that you've sucessfully got the mission + bonus done, if you done both you will receive 2.000 EXP.
