In Dark Cloud 2, it seems very easy to die to enemies. Enemies are just too hard to kill, and do way too much damage. There is one thing that can help you survive longer: Potato Pies, Witch Parfait, and Eden Fruits.
These items are scattered around Palm Brinks as well as the future world at different points of the game. As you adventure forward and change the future, new small chests, called “Miracle Chests”, will spawn in the future world.
