Unlike other stages, this mode allows you to keep dealing damage to a boss within a single stage.
Unlike bosses in normal stages, this boss is not defeated even when its HP reaches 0. Rewards increase each time you deplete an HP gauge.
Main rewards include Gold and other items.
There are also rewards based on the number of Boss Attack attempts used.
■ Seasons
Boss Attack uses a seasonal format.
The boss, rewards, and attempt-count missions change at set intervals. High scores, rankings, and attempts are reset.
Each season has an event period and an attempt period, and Boss Attack can only be played during the challenge period.
Even after the challenge period ends, you can still check that season's rankings and boss during the event period.
■ High Score Rankings
These rankings compare all players based on the score earned in a single Boss Attack attempt.
There are no ranking rewards.
If the season ends while you are playing, your score will not be reflected in the rankings.
■Attempts
You can play by using the attempts set for this event.
Attempts can be increased with Attempt Tickets or Herostones.
