1.) You must be the leader or a guild
2.) Do a Time attack on a dungeon during the week ( Monday - Thursday ).
This means you have to kill one or two dungeon end bosses.
If several guilds do a time attack, the one with the best time wins.
3.) On Saturday / Sunday can you now try to takeover the dungeon. ( Destroy the opposite dungeon stone)
Look into a Rappelz Wiki for more detalis ( e.g exact commands to create the TA or Siege Party )
