How to Play Edit

  • This event is to investigate the mysterious dimension under the Osaka Castle and collect koban.
  • The event is accessible via the event banner in the Front Lines.
  • This event has underground floors from 1 to 50. You can collect Koban by clearing the boss node on each floor, and by stepping on normal map nodes.
  • Event missions are available which will award rewards for completion.
  • Remodels:
    • It is now possible to repeat floors that have been cleared once.
    • When you repeat the floors and clear the boss node, you can choose the "Continue Investigation" button to repeat the same floor, or "Return to Citadel" to return.
    • Entering any floors will deduct 20 fatigue from each sword in your team. Repeating a floor will only deduct 10 fatigue.
  • In rare instances, Hakata Toushirou, Gotou Toushirou, Shinano Toushirou, and Houchou Toushirou will drop from the boss nodes on specific floors.

Notes Edit

170425 utc7 hakata bonus
  • There is no level limit for experience gain.
  • Kebiishi will not appear.
  • All clear rewards will be sent directly to your inbox. Please be mindful of the expiry date.
  • If you return to the citadel in the middle of a map, you will restart from the beginning of that floor.
  • Having Hakata Toushirou on your team will increase koban by 1.5x, Hakata Toushirou (Kiwame) by 2x. Any koban rewards received because of Hakata will be in green text.
  • Clearing 50 floors will grant you a small gift.

Tips Edit

  • 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.
