A Monster Box is a type of item which is critical to a Trainer's quest. It is used for catching and storing Monsters. The term "Monster Box" can refer to the specific type of Monster Box, or generally all varieties of Monster Boxes. Currently, up to six Monsters may be carried by a Trainer with Monster Boxes, while any number of Monster Boxes may be kept in the bag for later use. Monsters that are caught when your team is full will be automatically transferred to your storage at the Monster Center. The strength of a Monster Box is determined by how much it raises a wild Monster's catch rate, and may in fact vary depending on the conditions of the battle. Monster Boxes limit the power of Monsters, effectively taming them while they are inside the Monster Boxes.
Though the technology behind the Monster Box is currently unknown, the basic mechanics are farily simple. In a battle with a wild Monster, once the opposing Monster has been weakened enough, the Monster Trainer may throw a Monster Box at the Monster to attempt to catch it. When the Monster Box hits the Monster, it will open, convert the Monster to a unknown form of energy, pull it to its center, and close. A Monster in this state will then attempt to struggle to escape, and if it succeeds the Monster Box will be destroyed. However, if the Monster does not succeed in escaping, it is captured.
Types of Monster Boxes
As of now, there are 26 different types of Monster Boxes, all differing from each other in some effect. Most Monster Boxes increase the catch rate of some Monsters based on their type. A list of all the Monster Boxes, along with the description and price of each, can be found directly below.
