I joined only two months ago. I think I can relate to how u feel. When I first started here I felt bewildered becuz there isnt any sites/good guides. But the good thing is, a lot of nice ppl will answer your questions in forum :)
Anyway, you get new skill points at every second lvl, like lvl 2,4,6,8 etc. 20 is the highest lvl. At lvl 10 and 20 u get 2 skill points instead of one. U can lvl up only by doing quests and getting xp. Dont spend ur gold on buying armors and weapons now. U get gold and gears from quests.
Good luck with the game :drinks:
P.S. This game has no crafting skills. All skills are combat based. Shamans and druids have healing skill.
