Boss Drops & Rare Materials
The endgame loop is built on rare drops. Here is what each one does, what it is worth, and whether to sell it or craft with it.
Key Drops
A high-value boss drop used for endgame crafting. Its perfect price is worth checking before you sell — it funds a full shop level on its own.
Required to unlock deeper Vault floors and rare ancestral blueprints. Hold it for progression unless you urgently need gold.
Wave-based challenge rewards legendary relics, gold and unique weapon materials. The fastest repeatable source of blueprints for the blacksmith.
Sell or Craft?
If you already own the blueprint, crafting almost always pays off long-term — better weapons mean faster, safer runs. If you are stuck short of a shop level, the high-value boss core is the fastest gold injection in the game. Check each relic’s perfect price before you decide.
