Don’t remember how it works but yeah, it should at least damage them severely.
Kind of the whole point. Not all of them would get up as rubble whatevers. Only the non-pulped ones.
Would also serve as a consequence for taking the “easy” way out. (Other than the loud noises you cause, that is.) Burning a building down or however you choose to do it. I know I’m in the habit of luring a huge bunch of bad guys into regular houses, shutting doors and then lighting the walls on fire as I leave. It tends to work. Not so great when playing with wandering hordes but otherwise it’s a simple solution to a big problem. Too simple.
Punishment.
