Because Icon didn't want Klaus and the others wasting too much time, she led them through a path that had little to no treasures. This hastened their journey through the various floors.
Of course, she was not stingy, so she made sure every last one of them found something that was better suited for them.
By the time they got to the 6th floor, only Klaus and Princess Evren remained without a treasure.
However, now that they had reached the 6th floor, she would be gaining a treasure too, and Klaus's is waiting for him on the 7th floor.
Rory got her hands on a stone-like item that could be used to refine her bow. While it had become much stronger after the Burning Angel blessed it, now that it had become a soul weapon, feeding it treasures would greatly improve it.
Icon made sure she had that. She knew all the treasures in the jade vault, and so she picked the ones better suited for people following her master.
