well, about a guy (that's you), that starts as a visitor, it needs to choose a 'job' (or class) to be, you can be a hawker (bow & fast), a knight (swords), muse (magic),dealer (guns & expert at trade)...
you need to choose what you want to be.. then, you can evolve into a second class, that is a expansion of your class, which has more attacks...
for hawker, the 2nd classes are scout and raider:
scout: goes more to the side of archery, to have devastating attacks with his arrows
raider: evolves into a melee fighter, wh9ch depends on speed, camouflage, etc.
yo just have todo missions and get money, buy skills, explore the land, and, when your level is high enough, you go into another world...
