Lineage's stat, monster, and item system was originally largely borrowed from NetHack with MMO elements added. Players can choose one of five character classes: Elf, Dark Elf, Knight, Prince, or Magician. Princes are the only class that can lead a blood pledge (which is Lineage's term for a guild or clan). Dark Elves were introduced to the game after the other classes. Game play is based primarily upon a castle siege system which allows castle owners to set tax rates in neighboring cities and collect taxes on items purchased in stores within those cities. It features classic RPG elements reminiscent of Dungeons & Dragons, such as killing monsters and completing quests for loot and experience points, levels, character attributes (charisma, strength, wisdom, etc.), and alignments (neutral, chaotic or lawful). A characters alignment affects how monsters and town guards react to the player's character, often turning hostile to chaotic players and attacking on sight. Player versus player combat (also known as PVP) is extensive in Lineage. Players can engage in combat with other player characters at any time as long as they are not in safe zones such as cities. By joining a "bloodpledge" (an association of players almost like a clan in other games) players become eligible to engage in castle sieges or wars between bloodpledges.
