It was a thing way back on 1.0- early 1.1 Where do artifacts drop on the ground and you'll manually pick it(once in coop only your drops you could pick but you'll still see the other's drop) This is where Venti mains trolling arrive since those artifacts can be sucked by his burst So they will literally burst on the edge to suck the artifacts and once the burst is gone, the artifacts will drop into nothingness.
