The short answer
The Jaguar Door needs three different cast pieces. Budget 15 Coal and 24 Scrap Metal for those three casts alone; access keys cost extra.
Your route at a glance
- Find 3 different molds
- Return each to forge
- Cast 3 distinct pieces
- Return to Jaguar Door
Progression schematic, not a geographic map. Detailed steps and version limits below.
Look for three molds
- The room beside the large keyhole.
- The ladder route above the room next to the large forge.
- Behind the Iron Key door, opposite the Prison Key chest.
Molds are carried objects. Allow for the return journey and your stamina.
Cast and return
- Bring a mold to the large forge.
- Supply 5 Coal and 8 Scrap Metal for its casting.
- Repeat with the other two molds.
- Take the three distinct pieces to the Jaguar Door.
Keep the access budget separate
The total above covers only the Jaguar pieces. Any Iron Key or Large Key you still need is an additional casting. Old Demo footage may show an unavailable mold; this guide targets the full release.

Mold route and casting costs follow NPC Tips’ launch research. Check the forge prompt if your installed version differs.
