Hunter's Bestiary & Sanctum Boss Reliquary

Hunter’s Bestiary & Sanctum Boss Reliquary

Turn your Spyglass into a research tool, master the creatures you encounter, and build a trophy hall that strengthens your base.

Observe a living creature through a vanilla Spyglass for one uninterrupted second to earn research. Study new specimens or defeat creatures to increase your mastery of each species. Your discoveries survive death.

Study and master creatures

• Rank I: Reveal health and armor through your Spyglass and take 5% less damage from that species.
• Rank II: Deal 12% more damage to that species.
• Rank III: Deal 20% more damage, take 10% less damage, and gain a 25% chance of doubled mob XP.
• Browse discoveries in a searchable Bestiary Tome with 3D creature previews and research progress.

Build your Sanctum

Collect five soul relics associated with the Elder Guardian, Warden, Wither, Ender Dragon and Breeze. Relics also have survival crafting recipes.

Mount them on Reliquary Pedestals to display floating, rotating trophies and project themed auras, including underwater exploration buffs, night vision, fire resistance, regeneration and movement bonuses.

Each active pedestal reaches 48 blocks. Place three distinct relics within 16 blocks of one another to activate Cathedral Synergy, expanding their range to 96 blocks and granting four absorption hearts. Redstone pauses individual pedestals.

No generated structures are required—design your own cathedral, museum or trophy chamber.

Requirements: Minecraft Java Edition 1.21.1, Fabric, Java 21 and Fabric API. Install the mod and Fabric API on both the client and server.
