In Mantle of the Keeper, players take on the role of one of six Chosen that the Ascended have selected to compete in the Keeper Trials. Players must leverage their Chosen`s unique combat style and favor abilities to gain the upper edge on their opponents in battle. Each round, players will strategize how to traverse the arena`s terrain, avoid hazards, and play their Chosen`s individual deck of cards to deliver attacks and devastate their foes. Players can face off in a free-for-all or choose to divide into teams to utilize each other`s strengths to defeat the opposing players.
