To begin playing Lineage II, players create a character as their avatar in the game's medieval-style virtual world. All the races start off at Talking Island. Players can choose from either fighter or mystic professions at the start, except for Dwarves and Kamael which are only able to select the fighter profession; this choice acts as an archetype for later profession options. Each race has its own set of classes, even if humans, elves and dark elves have a lot of classes that are very similar to their counterparts in the other two races.As players kill non-player character monsters, they accumulate experience points and skill points.As experience points accumulate, the character's level increases, meaning various attributes of the character are augmented. Players purchase and then upgrade their character's skills using SP. Players can play alone or as part of a group to fight monsters and complete quests for new skills, experience points, and items. Player versus player (PvP) is a significant portion of the game. The game provides many social, political, and economic aspects which are developed through the community and by the actions, in-game, of single players. Lineage II features siege warfare like the original. To make sure PvP stays under control, the design includes a Karma system that provides negative consequences for killing other players when they are not fighting back. When being in a chaotic state (karma number higher than zero) with a PK count of 5 or more, players have a high probability of dropping items after being killed.
