http://forum.blackdesertonline.com/index.php?/topic/92143-siege-warfare-manual/ Things to note: (will update as needed) Fort Repair requires polished stone (for Node Forts) and Blackstone Powder (for normal Forts) When the fort’s durability is down, all guild members can jump in and repair it. This way, even the guild members with low level or mediocre gear can contribute to the guild. Players who excel at combat skills can function as combatants, and players whose main trade is not combat can contribute to the guild in many other ways, such as controlling Flame Tower or Hwacha, riding on an elephant, or repairing the fort.
