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 also by stepping on normal map nodes. The reward for clearing the 50th floor is the new sword Gotou Toushirou.
- If you return to the citadel in the middle of a map, you will restart from the beginning of that floor.
- 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 will replay the 100th floor for the remainder of the event.
- In rare instances, you can obtain Gotou Toushirou or Hakata Toushirou by defeating the boss on the 100th floor.
- Players who finish all 100 floors will receive a modest souvenir as a commemoration. It will be the same background as the first event, but those who already have it will be given something different.
Notes[]
- 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 and resource rewards by 1.5x. Any rewards received because of Hakata will be in green text.
Tips[]
- 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 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.
- All clear rewards will be sent directly to your inbox. Please be mindful of the expiration date.
