finding a mod/plugin/modpack

For what loader are you looking for?
Fabric or Forge?

I'll try search for this mod.

I doubt you can find it by searching because it's usually just YouTubers popping up doing videos like "If I take damage everyone else takes damage too".

I'll update you if I find anything.

Very sorry to disappoint.

I searched far and wide but there's no trace of that type of mod anywhere.

I doubt I can find it.

I am very sorry to disappoint that I can't find it.
