Stone metamorphosis

Stone metamorphosis was a transmutation spell that changed one type of stone into another.

Effects
On casting stone metamorphosis, the caster changed one type of touched stone into another with the affected volume increasing with the caster's skill. For example, one could turn crumblestone on the ground into granite to evade the hazard. However, there were some limitations. First, one could not become rich by means of this spell, because stone metamorphosis could merely change one stone in another whose monetary value did not change. Second, gems, both precious and semi-precious, were outside of this spell's capacities.

Components
Stone metamorphosis required somatic, verbal, and material components to cast. The required material components were a grain of talc and a chip of obsidian. Cast as a divine spell, stone metamorphosis's material components were substituted with a divine focus.

History
At latest by 1372 DR, a kind magical staves called staff of stone was developed. The crafting of these staves required among others the casting of a stone metamorphosis spell.
