I heard a rumor that The Plane of Mischief is an endless dungeon with teleport checkpoints you get after beating contested bosses, and that the trash mobs have a super rare chance of dropping better loot than the checkpoint boss loot chest. I can't find the entrance, though. I ran all over every little bit of water in the Velious content and there's no little clicky house thing. How can I gain access to this really awesome sounding dungeon? Thx
