Book of Mastery vs Tidekeeper: Which to Inherit in Idle Iktah

Player question: Should I prioritize carrying over the Book of Mastery or the Tidekeeper into my next Legacy run in Idle Iktah?

I like these games and play them myself. Complete guides are hard to find online, so while playing I collect community experience from Reddit, add a little of my own notes, and put this site together—hoping it helps. Thank you.

Quick answer

Recommendation The choice between the Book of Mastery and the Tidekeeper depends on your session style rather than a single superior item. If you play actively and regularly complete writ tasks to trigger proc bonuses, carrying over a completed Book of Mastery preserves significant accumulated progress. If you play mostly idle and already slotted three Black Pearls into your Tidekeeper, the Tidekeeper provides vastly superior passive gathering acceleration across all early biomes without demanding active micro-management.

The Playstyle Trade-Off

Community Knowledge In r/IdleIktah discussions, players repeatedly contrast the Book of Mastery against the Tidekeeper as top contenders for the limited three-stack Inheritance perk[1]. Both items represent substantial pre-Legacy grinding investments, but they serve opposite play patterns.

Book of Mastery: Value & Writ Scaling

Observed Game Fact The Book of Mastery accumulates writ completions that grant compounding bonuses to skill progression. Carrying it forward via Inheritance preserves completed progress into the fresh run, avoiding the need to re-craft and re-rank writs from scratch.

Community Knowledge A fully slotted Tidekeeper—equipped with three rare Black Pearls—is widely celebrated by community veterans as a transformative passive gathering engine[2][3].
