In the Challenge Phase, players have over 10 days to challenge a variety of PvE chapters, each with multiple paths leading to a Chapter Boss. Players earn rewards for clearing each chapter and will be ranked based on their progress.

For each server, when the total number of players on the server that has cleared a certain chapter reaches 10, 20 and 50, all players on the server will receive rewards. Rally your friends to join and fight for the common goal of more loot!

Some monsters in Challenge mode will be randomly replaced with the hero squads of online players of appropriate BR. The bosses in later chapters can also debuff your squad with various effects, which really ramps up the difficulty. Luckily you can also unlock helpful buffs by making full use of Talent Tree system in the Challenge Phase.

The final champions in each division will not only gain special titles, but also have the privilege to purchase highly discounted items in the shop.
