Quote from ofcourse:
and huh?
At Rakanishu, he directly activates the stones and ignores the monsters (killing Rakanishu is faster anyway
All he means is that the guy with the scroll of inifus should activate the stones and let other people kill, because they can kill Raka before the stones are all active, so the guy with the scroll helping to kill wouldn't speed it up. I hope that was clear.
