Tips
Force Fields > Physics Properties > Untick “Affect location”. Leave this option ticked and simply Cache > Bake to refresh.
Add a wireframe with strength=0 to Icosphere to hide emitter but still see output in viewport.
Use render borders when you are in camera view. This will render only what’s inside the camera and speed up preview.
The paths can be animated with hooks, baked bounce exported and then not max out your memory.
