I realized that it would have probably been a good idea to release the fire sparks particle as its own standalone sub-resource.
If you only want to use the particle, it is a separate VAR file that can be separately downloaded from this resource page, reducing extraneous resources dependencies if you don't want any of the other asset dependencies that come with the whole prefab.
The original subscene is unchanged, and still retains its own copy of the fire spark particle, in order to prevent any chance of any resources that already depend on it from breaking.
If you find any issues, please let me know.
