Tearing Earth

Centered around a spot in your line of sight, you cause the earth to crack and explode in a 165 ft diameter circle, summoning lava – molten rock – from below to surge forth in a flood to attack. This spell damages the surroundings. 

Any creature within the area of effect must make a dexterity saving throw. A creature takes 10d10 bludgeoning damage and 8d12 acid damage on a failed saving throw, and half as much damage on a successful one. On a failed saving throw, any metal object carried by a creature is heated to white-hot. Any creature in physical contact with the objects takes 2d8 fire damage for six rounds.
