Raid Battles

Raid battle system interfaceThe Raid Battle interface on the website

The "Raid Battle" system is a side event open to all osu!taiko players (not just tournament participants) for the duration of the tournament, where players cooperate to defeat boss characters by submitting scores on Project Prism's tiebreaker beatmaps.

Players can deal damage to the boss by setting a score on any difficulty of the tiebreaker for the current tournament stage, then submitting it via the website. Difficulties are available from Kantan, meaning beginners are also welcome to participate.

Each boss is associated with a tiebreaker song release each week starting from the Round of 32, with an introductory round available before then.

Characters by tournament stageCharacters associated with Project Prism's original tournament tiebreaker songs

A list of missions is presented for each stage, which can range from "passing every difficulty" or "completing a map with Flashlight". Completing these earn players rewards on the website, namely story events or "gacha pulls", which are tickets for redeeming random character cards that multiply damage dealt to the boss.

Both individual score and total damage dealt are recorded onto their respective leaderboards. After enough damage has been dealt during the stage and the boss's HP reaches 0, the top players in both leaderboards receive additional character cards as reward.

Even after being defeated, bosses are still available such that players can deal damage and complete missions until the event ends.

Detailed information can be found on the website.



  1. Registrations must be submitted through the website.
  2. All registered players will undergo an initial screening process by the osu! staff and any players who do not pass the screening will not be eligible to participate in the tournament. Results of the screening will be announced in the Discord server.
  3. Players must join the Discord server to be eligible for the tournament.

Qualifier details

  1. All players will play through a special pool comprising of 5 brackets: No Mod, Hidden, Hard Rock, Double Time, and Free Mod.
  2. The mappool will consist of 10 maps, 3 No Mods, 2 Hiddens, 2 Hard Rocks, 2 Double Times and 1 Free Mod.
  3. Players are allowed to play through the mappool twice in their designated lobbies.
  4. Players may choose to skip maps (only on the second run) or the second run altogether if desired.
  5. The mappool must be played in order from top to bottom. Players are not allowed to shuffle the mappool order or skip any maps during the first run.
  6. Only the highest score of each map out of the two runs will be taken into consideration for seeding purposes.
  7. An optional 5-minute break can be given between the first and second runs if any players in the lobby request for it.
  8. Only the top 64 seeded players will advance to the bracket stages.
  9. Seeding will be made with the average rank of each player on each map.

Match rules

  1. Players are required to be present at the times of their match. A reminder in the form of a Discord ping will be given to the players 15 minutes before every match.
  2. Invites to the room will then be sent out 10 minutes before each match.
  3. Failure to arrive on time will result in the following penalties:
    • 5 minutes: Player warmup will be skipped
    • 10 minutes: Player map ban goes to opponent
    • 15 minutes: Player loses by default
  4. Warmups must be sent to the referees at least 30 minutes before the start of the map. The warmup must be less than 3 minutes in length and not contain inappropriate content. The referee reserves the right to reject maps that they deem to be inappropriate.
  5. At the start of each match, players will be asked to !roll to determine who picks or bans first. The player with the higher roll will get to pick first and ban second.
  6. Banned maps and tiebreakers are not allowed to be picked throughout the match.
  7. Each player will be given a maximum of 2 minutes to select their picks. If a pick has not been decided before the countdown timer ends, the map will be randomised with !roll.
  8. After a map is decided, players will then have a maximum of 2 minutes to ready up before the referee forces a start.
  9. Players should ensure that they have all the maps downloaded before the start of their match. In the event that a player is missing a map, they will automatically lose the point if they are unable to download it within the 2 minutes given.
  10. Players may ask for a "tactical timeout" during a match, which will add an extra 2 minutes to the timer. This can only be used once per match.
  11. A rematch of the same map will be given if a player disconnects within the first 30 seconds of the map. Any subsequent disconnections on the same map will be treated as a point loss.
  12. Lag is not a valid reason to restart a map.
  13. In the event of a tie in scores, neither player will gain points and the map will be played again.
  14. In the unlikely event that both players get a tied score twice in a row on the same map, the map will be nullified, and another map needs to be picked by the other player.
  15. Failed scores will be counted.
  16. If both players reach match point (requiring 1 more point to win), the tiebreaker map will be played.
  17. Unexpected incidents will be handled by the referee or host.
