Fate Fabric is a late-game rare resource obtained primarily by completing Fated List prophecies and by defeating specific bosses under special conditions. It does not appear in standard rooms and cannot be farmed through ordinary combat, making each copy genuinely scarce. Tracking unfulfilled prophecies before each run and planning routes around achievable objectives is the most reliable acquisition strategy.

• Crafting high-tier Cauldron Incantations that unlock major permanent upgrades
• Unlocking upper-rank Arcana Cards in fate- and constellation-themed categories
• Fulfilling material requirements for select NPC exchange events (e.g. Moros, Arachne)

Because Fate Fabric is both rare and in demand across multiple upgrade tracks, it should never be spent without first confirming which use delivers the highest current priority. Each copy counts — spending one carelessly can stall an entire progression branch. Establish a collection habit early by keeping the Fated List active and targeting achievable prophecies every run.
