The amount of Experience points a player has determines his or her King Level. King Level indicates the level of the player's Crown Towers. Experience cannot be gained by simply battling. Experience is gained by upgrading cards and donating cards to clanmates. Experience gained from donations vary based on the card type donated (1 Common card is worth 1 , 1 Rare or Epic card is worth 10 ).
