Summoners War: Chronicles is an Action RPG based in the Summoners War Universe.

To start, you will choose between a selection of three summoners – who will then become your main avatar. Each of the three is bestowed their own unique power, skill, specialty. There are several modes in the game – each one nurturing some kind of reward that you may claim. These three are the Dungeon, Ascension, and Raids modes – the lattermost a multiplayer type that allows you to battle alongside friends.  

You can also gather, mine, and fish in between battles – so as to recharge your character and allow resources to flourish.
