Sam sat before the Left side Platform as his target was the Transference Scroll. He doesn't know what they are, but he can guess from the name itself, it might be an escape item which could save him in an unprecedented threat.
As Sam started his refining, the rest also got to their own choice, some of them including Arthur focused on the Sabre.
There are only four people for the Transference scroll including Sam himself.
But right now, Sam is in a very shitty mood and he might stay in that mood until he finds a way to vent that so, he took out his two swords and stabbed them both beside him.
He doesn't want to compete with these guys for this, since he laid his eyes on this, he is going to get what he wants and he doesn't have enough patience to fight with these guys.
And just like that, he is alone in front of that platform.
