Before you plan around this record
The source snapshot labels this item 1.0.0. We checked v1.0.5 patch impact on 2026-09-26, not every spawn in a live save. Unspecified size, drop rate, exact time, unlock and stock rotation are deliberately omitted.
Sources and version context
1.0.0 dataset; v1.0.5 impact reviewed. Dataset checks are separate from the current game version; a patch review does not claim that every granular value was retested in-game.
