How to Play

 * Floors 1 to 50 are made to be accessible to all players. You can collect Koban by clearing the boss node on each floor, and by stepping on normal map nodes. The reward for clearing the 50th floor is the new sword Houchou Toushirou.
 * Floor 51 onwards is the challenge stage. Enemies from hereon are stronger so you should attempt these floors in accordance to the level of your team.


 * Once all floors have been cleared, you can only replay the 100th floor for the remainder of the event.
 * In rare instances, Hakata Toushirou and Gotou Toushirou will drop from the boss nodes from Floor 1 until 100, while Shinano Toushirou will drop from the boss nodes from Floor 51 until 100.

Tips

 * After defeating the boss on each floor, you will automatically proceed to the next floor.
 * Troop count is restored at the end of each floor, as if one had returned to the citadel at the end of a map.
 * Enemy strength and floor difficulty increase every 10 floors.
 * Swords accumulate fatigue as they progress through floors.
 * Since you cannot confirm fatigue levels during sortie, it is recommended to return to citadel at regular intervals to monitor fatigue.
 * All floors within the event are normal day maps. Ootachi and Naginata have an advantage, however putting Tantou in your team will slightly increase the chances of stepping on resource nodes.
