The objective of the game is to defeat the opponent's king. Each unit (in exception to the Bishop) has a normal attack. The bishop cannot attack but has the ability to heal other units as an ability. Each unit can perform at least one ability. To see the abilities of a unit, you can toggle on his normal attack mode to his abilities list by doing alternate clicks on the unit. Some abilities will have a resource (fire, earth, wind or water) cost associated with it. Resources can be obtained by moving a unit into a tile of that resource.
