Earn $BDD

Challenge the boss every day, and win the BDD according to the highest level successfully cleared that day. The system will issue BDD rewards through the game's email notification the next day. Merge more advanced heroes and pass higher levels to get more BDD rewards.

Participate in point competitions in the arena, initiate challenges, and get the arena ranking to get daily BDD rewards. Arena rankings are held for 30 days per season, and the ranking data will be cleared and restarted at the end of the season.
