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.
