Requirements: Oak Planks, Saw, Hammer, Demon Butler, Servant’s Moneybag with GP in it, Dungeon Corridor, 74 Construction, Runelite Zoom in all the way All the way in (enable expand inner zoom limit) Call your Demon Butler Have him un-note 20 Oak Planks Hold the number “1” down on your keyboard and proceed with the method as demonstrated. By having the door built when he arrives, he is effectively trapped on one tile. This eliminates the need to move your cursor every few seconds to interact with the butler. With good attention and few mistakes, it is possible to maintain over 500k XP/Hr with this method. With perfect ticks, over 510k XP/Hr is maintainable. The rest of the video is just further demonstration. Hope this helped!
