How to Play Edit

  • Floors 1 to 20 are made to be accessible to all players. You can collect Koban by clearing the boss node on each floor, and also by stepping on normal map nodes.
  • If you return to the citadel in the middle of a map, you will restart from the beginning of that floor.
  • Once all floors have been cleared, you will replay the 20th floor for the remainder of the event.
  • In rare instances, you can obtain Hakata Toushirou by defeating the boss on the 20th floor.

Notes Edit

  • There is no level limit for experience gain.
  • Kebiishi will not appear.
  • It's not possible to return to a previous floor once it's been cleared.
  • Having Hakata Toushirou on your team will increase koban rewards by 1.5x. Any rewards received because of Hakata will be in green text.

Tips Edit

  • After defeating the boss on each floor, you will automatically proceed to the next floor.
    • Troop health 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 5 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.
  • Clearing specific floors will give certain rewards in addition to Koban.
    • Troops and swords will be sent to the mailbox if your inventory is full.

The following rewards are given for clearing each floor of the Underground Treasure Chest map.
