Opal and Fire Opal use different local geode pools

The local Artifact Trove (O)275 drop list contains neither 564 nor 565. Artifact Troves are therefore not an Opal farming source.

Reloading the same opening does not reroll it

Geode and trove results follow the deterministic opened-geode sequence. Saving immediately before one opening and repeatedly reloading without changing that sequence repeats the result. Opening a different geode first advances the sequence; a predictor can describe the sequence for a compatible save and game release, but it does not turn Artifact Troves into an Opal pool.

Normal uses

• Donate the first Opal to the Museum if it is still missing.
• Use Opal as a Sewing Machine spool item for its local tailored shirt result.
• Use its color_light_cyan context in the dye system.
• Sell duplicates for their base value or keep them for requests and decoration planning.

Bracketed animal names are not a normal repeatable source

Naming an animal [565] does not make ordinary petting award a Fire Opal every time. Historical item-ID name spawning depended on a supported build rendering or speaking the bracketed name; platform and version behavior differ. It should not be presented as a stable acquisition method.
