Unlock Qurious Melding: Vigor and Cyclus after Amatsu

Melding Pot after the Amatsu urgent quest; speak with Elgado’s merchant and inspect Qurious Melding options.

Before you go

Reach MR10 and unlock the Amatsu urgent quest The Sun Will Rise Again.
Complete earlier Sunbreak progression gates required for the endgame melding options.

At the Quest Counter, check that The Sun Will Rise Again is available and select the Amatsu hunt.
Prepare a late-story Master Rank loadout and complete the urgent quest.
After the clear, return to Elgado and speak with the relevant merchant/NPC if the melding option has not appeared.
Open the Melding Pot and verify Qurious Melding—Vigor is listed.
Check for Qurious Melding—Cyclus and read its talisman-input requirement.
Use afflicted materials in Vigor only when ready to create talismans; Cyclus requires eligible talismans from the system.
If the options remain unavailable, clear outstanding progression prerequisites and recheck the Melding Pot rather than grinding research levels blindly.

Capcom describes Vigor as using afflicted materials and Cyclus as specifying a skill from talismans created through Qurious Melding.
Amatsu is a progression gate, but the menu may also depend on earlier urgent quest/story progression.
Do not expect Cyclus to accept ordinary talismans if its display requires Vigor-created ones.

This is a one-time unlock route; after the options appear, use the corresponding guides for ongoing talisman farming.

Do not confuse the unlock with the separate Anomaly Research Level weapon-augment gates.
Do not assume beating Amatsu alone bypasses earlier endgame prerequisites.
Do not spend materials until you have checked the Melding Pot option and inputs.

Stop once Vigor and Cyclus are visible and their input requirements are understood.
