[quote]Those are attribute points ;) You can spend skill points by buying skills from the Skill seller :D (he's called Sir Bertran)
Then I guess I'm lost as well. I don't think I've used any skill points. What kind of things do you buy with them?
Skills. You get free skills from many quests, but you can also buy them at 'skill traders'. These skills cost a certain amount of gold - 50 for the first, getting increasingly expensive for each skill, until it hits 1000 - plus one skill point. No more skill points = no more skills.
You receive skill points for completing missions, and for each full bar of experience after you've hit level 20 (maximum level allowed in GW).
Normally, skill points aren't a problem, you'll usually have enough to buy whatever skills you want. When you start collecting every single skill in the game, you might start encountering a slight shortage though ;)
