Magma Stone

The Magma Stone is a key item introduced in Generation IV, though unobtainable as an item until Generation V.
It is a red stone that was created long ago when boulders melted together in hot magma, then hardened into one stone. Remains of the magma is sealed inside the stone.
==Effect==
It was once said that the Magma Stone had the power to control the Legendary Pokémon Heatran, who resides in Stark Mountain.
In Diamond and Pearl, Buck takes it from Stark Mountain, but returns it on the advice of his grandfather.
In Platinum, Charon takes it in order to try and control Heatran, but Looker takes it from him and gives it to Buck, who later returns it.
In Black 2 and White 2, if the player brings the Magma Stone to the lowest floor of Reversal Mountain, a Heatran is encountered.
