A Wishing Stone

A pearl-like stone of unfathomable power. It contains the ability to warp the fabric of reality to one's will. Only the phrase, "I wish..." is needed to activate its inherit ability.

Though the stone does have its limits. It generates heat for each wish it fufills. The grander the wish, the more heat it must produce. And upon hitting a certin level of pressurized energy, the stone may begin to crack. Upon breaking, its hold on reality will collapse with it, taking its alterations down in the process.
