The Ninja Tower is an event which challenges players to see how far they can climb! This event is open to any player who has reached level 20. The goal is to climb to the highest level possible, with the best score. Players will receive rewards based on their rank at the end of the event. Scoring in the Ninja event is based on the Highest Floor reached and the cumulative scores from each floor played. It is not possible to replay stages once they have been successfully completed, nor can a team be revived once it has been defeated.

The Ninja Tower Stages feature Oni Curses, which, if they are not destroyed in time, will curse the targeted hero. Once a hero has been cursed twice, they can no longer be used in the Event.

In addition to the Curses, after certain stages, players will have an opportunity to choose an Oni Blessing. These blessings are buffs that will remain active on all your Heroes in the Ninja Tower event for the duration of the event. The Blessings and Curses cannot be removed or dispelled.

The Ninja Tower Event Stages are much more challenging than elsewhere in the game. Even the most powerful heroes with the best tactics are intended to face very tough battles in this Event!
