Diver Down shipped in the same September 25, 2026 update as Crazy Diamond Requiem. It is a quest on top of Stone Free, and the last trade deletes Stone Free.
What you need first
- Stone Free, from a Mysterious Arrow. Obtainment videos put it in the same roughly 2% to 2.5% band as other rare arrow Stands.
- A level gate. A September 25 summary says level 40 or higher.
- Prestige 1 is also named in the same update's showcase as a requirement for Pucci's new dialogue. Meet both if you can, and read Pucci's line if one of them is still short.
Steps
- Summon Stone Free.
- Go to Diavolo's Castle and talk to Pucci. Ask about the trade. He sends you to Anasui.
- Anasui is near the cosmetic shop. Tell him you are friends with Jotaro. He asks for Jotaro's disc.
- Jotaro Part 6 drops that disc. It is described as a rare drop, so budget more than one kill.
- Bring the disc back and confirm the trade. The warning on the trade says Stone Free is deleted and you receive Anasui's disc.
- Use Anasui's disc to finish Diver Down.
Do not confirm the trade if you wanted to keep Stone Free for a second account or a different build. There is no documented undo.
Diver Down is a team-fight Stand in early player reactions, with shielding tools that matter more in groups than in a pure 1v1. It is new enough that October 2, 2026 tier write-ups still left it unranked. Learn the disc trade first, then decide if you like the kit, instead of treating a tier letter as the reason to delete Stone Free.
