Summons

Summons are a way to power up your Troops. All of your Troops begin at the Common Rarity. By spending Coins you can collect cards which will increase the rarity of your troops.

Start by clicking the Summon button on the bottom of the main screen. From there you can choose if you are pursuing upgrades for Primary or Secondary Troops. Each summon that you buy will earn you random cards. If you are lucky and collect a rarity card for a Troop which is higher than its current rarity, you can automatically increase that Troop's rarity to what is shown on the card. Additionally, as you collect cards of the same rarity of your Troop, you can eventually increase your Troop's rarity one level.
