Workshop
Use the four materials glue, thread, type and ink to craft spirit treats, boss-trial supplies and bookplate blocks. Materials come from pastimes and other sources.
Handwork
Collation, type picking and catalog matching are three puzzles using only numbers and symbols, with no time limit. Completing them grants workshop materials.
Boss Gauntlet
Fight defeated chapter rulers in chapter order. Trial rank has no cap, with six constraints and five leaderboard entries. No random numbers are used.
Seal Book
A 3×3 (9-cell) task card arrives after the first chapter ruler. Complete tasks such as defeating enemies, landing critical hits and opening Lecterns to earn stamps.
- Complete a horizontal, vertical or diagonal line for Gold and 2 Memory Shards.
- Fill all nine cells for 6 Memory Shards, Insight and bindery materials; a new card then arrives.
- Once per card, reroll an unstamped cell for a different task. There is no deadline and progress survives rebirth.
