Erupt

Erupt was a divine transmutation spell that caused a massive eruption of lava to spew forth from the ground, at a location of the caster's choosing.

Effects
The burst of molten earth encompassed an area hundreds of feet in diameter. Those caught within the molten eruption were severely burned, caught fire and, if they were wearing metal armor, were seared as if they were affected by the heat metal spell. The effects of the spell were catastrophic on the face of Toril; the land beneath the eruption was left charred and incapable of supporting natural life for a year's time.
