There are two Challenges in this mode, but only one of the two is at a time: Endless night and Demon Realm.
- Demon Realm: this Challenge requires you to deal as much damage as possible to the giant Boss, as your total damages inflicted will be calculated as their points on the Leaderboard.
- The Endless Night: players are required to slay as many minions as possible since the total number of minions vanquished in the battle will be calculated towards their points against others on Leaderboard.
Players have only 2 turns to compete for top rankings on the Leaderboard each day, so arranging your team formation wisely with your best warriors is highly recommended.
After the Challenge ends, players will receive Special Spinning Tickets corresponding to their rankings. Special Spinning Tickets will be sent at 0h (UTC) on next Monday.
