Combat
Both sides will draw one random card per turn. All cards have an activation time, indicated as the number next to its hourglass. That number of turns must pass after the card has been drawn before it can be used. You can place as many active cards onto the field in a single turn. Cards will only attack whatever is in front of them. If another card is facing them, they will damage it until it is destroyed. If no cards are present, it does direct damage to the opposing character. Runes will activate under specific situations and have varying effects on your opponent.
Encounters
Each encounter on the map is marked with a stars (from zero to three) to indicate how it was completed. One star is awarded for completing an encounter. Two stars are given for completing an encounter under the Medium difficulty setting while meeting special requirements. Three stars are awarded for finishing the encounter under the Hard difficulty setting with stricter requirements. Once an encounter has been completed under a three star rank, you may longer fight there. Encounters marked with a crown are Boss fights. You must complete them to unlock the next section of the map.
Myst Tower
This is a special area that can be explored only once per day, unless you pay gems. The goal is to get through a simple maze while searching for treasure chests and fighting monsters on your way to the stairs that lead to the next floor.
