Hmm I dont know, when I still played everything just came on its own, like for example I did a quest for a dragon scimmy and I got the ability to use gliders for example, I guess everything's kind of sawn together if you know what I'm saying. I liked slayer, got 85 slayer got a party hat out of that, kept on slaying and then levels and money came out of there, then again i would've never done it without voldy xD.
