Limited Events

Limited Events were introduced in version 2.10. Events consist of select songs which the player clears to advance their event progress. Event progress advances according to the number of Starlight Scores used. As the player gains more event progress, they will receive rewards such as Stabilized Sound, Starlight Score, Chiming Core, avatars, and eventually, secret songs.

**Secret Songs**

Secret songs must be unlocked by event progress. Once they are revealed, they become Sealed songs. Sealed songs can only be played using the event tracklist. By unsealing a song, the player will unlock it in their full tracklist. Songs that fail to be unsealed before the event ends will be unavailable for the player.

**Event Progress**

Event progress is gained by playing songs in the event tracklist, and each song requires a certain amount of Starlight Score to play. The player can either play any song they already own, or use more Starlight Score to pick a random song. Any event progress of a limited event will be reset to 0 at the end of the event and does not carry over to the next re-run period.

**Event Challenge**

Event challenge has been introduced in the Arcaea Collaboration Event. Event challenges may be separated into two sections: Mission and Puzzle. Clearing missions provide basic rewards (such as Starlight Score, Chiming Core and Stabilized Sound) and collecting all puzzles or completing the last Event challenge mission unlocked will invoke a boss song to be unlocked. Event challenges increase in difficulty as the player clears them, and the player can use Stabilized Sound to decrease the difficulty of a mission.

**Challenge Pass**

Challenge pass has been introduced in the Arcaea Collaboration Event. By purchasing the challenge pass, it will unlock the specified song directly and the second specified song will be unlocked after the event has been completed. If the challenge pass contains only one song, then the player must complete the Event challenge missions to unlock the specified song. Purchasing the challenge pass will also grant the player extra rewards when completing Event challenge missions and instantly completes all unfinished Event challenge missions at the end of the event. The challenge pass can only be purchased during the event period.

Only ONE challenge pass can be purchased for each limited event. If a challenge pass has been purchased during an event period, it carries over to the next re-run period of that same event. Event Challenge progress also carries over whether or not the challenge pass has been purchased before.
