AE Heart is a cross between a top down action RPG and a strategic board game. Playing as The Dreamer, you have 30 days to do as much to save your dying world as you can. By day, you arrange the buildings in your town in order to unlock new dungeons and progress farther in the game, and by night you enter the dungeons to collect the resources you need to grow stronger and build better buildings.
Boss of the "Diamond Rough" dungeon, an endurance battle where you must survive until you kill enough enemies to open a path to the center.
