Count "defeat four enemies with one explosion" when chain reactions are involved

The player blasts a barrel, which sets off two more, which finish several enemies. Did that take one action or three? And a different blast later should not add to the first. Here is how to trace every defeat back to the single act that started it.

Why this works

"With one act" is a question about cause, not about timing. Following each defeat back to the first thing the player did, through every blast it set off, credits one deed with everything it truly caused and keeps separate deeds apart.

When not to use it

Skip the tracing when the challenge is only "many in a short time", with no cause to follow. A plain time window is simpler there, and tracing would reject things players expect to count.
