Shiny Ball is a healing item that speeds up the healing rate during a period of time. With it's cost, 10,000 Gold, it's by far, the most expensive item in the game.

While arguing for it's pricing, this item is by far the most important item in later boss fights, because it completely negates the non-recovery rate in boss fights, constantly refilling the HP and MP of Nasir, even when he moves. As such, this item can defenitely be worth backtracking to Voloh.
