There are 5 character rarities; common, uncommon, rare, epic, legendary. Each character has 10 levels. To level your character, 3 of the same character (and level) are required. Use the upgrade screen to combine these 3 characters into 1 character from the next level. From level 7 onwards, only 2 cards of the same type & level are required to level up. As you upgrade characters their Attack Power & Health Points increase, sometimes even gaining a new ability as well. To view all of the different characters available take a look at the card library (coming soon). Each character comes with a maximum of 3 Abilities. Each ability heavily effecting the strategy in battles and allows you to make a diverse deck different to your opponents. Unless the character's abilities dictate otherwise, characters have a base movement speed of 2.
