This requires at least three Master Builders, Lightning power, and children for distraction. You must take down the blocking totem, which guards the entrance to the mausoleum. Drop at least one Master Builder on the totem to start taking it apart. Once you start to work on this totem, the guards and others from the mausoleum will try to rebuild it. Your builders will run away. Make sure they do not go far. Once the totem is surrounded by the guards, hit it with Lightning. When they run away, drop your builders back on it to tear it down. If any orange guards return early, keep them distracted with a child. When the red and blue masks return and start repairing the totem, hit them with Lightning again. When they leave, bring back your builders and keep tearing it down. Repeat this as needed until the totem is gone.
