Gather Players

• Dungeoneering in a group is always best, especially when it comes to lever rooms. Call every player back into the lever room and ask each person to stand at a lever. If you are on voice chat, turn the levers simultaneously with a command. If you are on typing chat, have someone count to three and everyone pulls their levers on three.
  
  

Use Gatestones

• The leader of your group receives a gatestone at the beginning of the floor. Additional gatestones can be made within the dungeon using the magic skill. If you do not have enough players to cover all the levers, drop a gatestone by an unmanned lever so you can teleport to it. This will save you a few precious seconds.
  
  

Skip the Room

• If you are alone or do not have enough players to sufficiently cover the levers, this room will harm you and use up limited food. Those who have worked an advanced dungeon before know how scarce and precious food supplies become when you are preparing to fight the boss. Avoid wasting food on this room if it is not necessary to get to the boss.
  
  

Carry Lots of Food

• For those who want or need to complete this room, it is imperative that each member of your team carry plenty of food in their inventory. That way, whether the monsters in the room or the room itself injures your team, you will all be prepared to avoid dying.
