Each progression on the map will reward the player with different items (such as Food or Gold) or present them with a battle. The destination room will have a chest to purchase with currency which will offer greater prizes. There is a certain limited amount of currency that can be earned within a period of time that resets every certain hours. The limit increases, after the next reset, every time a level is completed. The total tile progression cost of a level is distributed among the different paths inside it. Battles can be fought normally with no cost or can be won instantly in exchange for a certain cost. If a battle is lost, the player can purchase the instant win or wait a certain time before they can attempt the battle again. Each level contains a number of chests. One of the chests will hold a and the remaining chests will each hold a Dragon Piece for a limited Card-Segment Dragon. The position of the key is random and can be obtained from any chest. Once a key is obtained, the player can advance to the next level without having to open other chests. Opening all the chests is necessary to obtain the Card Dragon, but not to advance to a new level.
