Use crates to add ASMRS to your Index, but compare the live price, visible rarity label and your free slots before opening. No reliable public drop-rate table was found.
Crates are the entry point to the collection loop. Reviewed gameplay showed named stations in the world and a reveal flow that adds a toy to the player's collection. The visible labels included Chocolate Key Crate, Foam Ball Crate, Frozen Slime Crate, Cosmic Slime Crate and Squishy Dumpling Key Crate.
Those observations are useful for recognition, not for calculating expected value. The recordings did not expose complete content tables or probability percentages. A rarity word on a crate or toy is not enough to infer a numerical chance, and one observed pull does not prove a guaranteed result.
Prices are equally sensitive to updates. The $100, $2K and $25B examples belong to a Jul 30 video build. Check the station in your live server before saving toward one. A safe crate decision protects placement capacity and the next known progression requirement instead of chasing an unsupported best-crate ranking.
