Exsperience Points
There are XP bands you get for doing quests or looting them from other players, or by turning a lootable object in.
Yellow Xp bands are worth 5 xp. Blue: 50. Black: 100 xp. Green: 1o xp.
When loot someones xp you can only take 50 xp (ask them to give you the xp, dont take it from them.) unless your an assasin, you can steal an additional 50 xp.
People can make up there own quests and get some the amount of xp that is used in the quest just for hosting the quest and the people that are monsters or people in the quest to fight get xp for doing it to.
