SK Book (Pearl Bay Magazine on CN) is a set of monthly missions that feature a rotating roster of 6 characters. Players are rewarded with stamps for each mission they clear, with rewards for each stamp milestone. The rewards also include SK Tickets, which can be used to vote for next month's featured characters.
The SK Book has been on hiatus since March 2021. Players can still use bookmarks to unlock previous issues and claim their rewards.
The SK Book also features 4 ship traits every month, and the player can assign up to 4 ships to each trait for a stat bonus.
Voting for next month's ships requires SK Tickets
