Volcanic Terrain

You alter the composition of the ground around you, turning it into fiery magma. 30 ft. around you, the ground turns into magma for a duration of 1 minute. Anything touching the ground within the range is affected each round they are in range(does not affect flying creatures unless they touch the ground). Each creature in a 30-foot-radius centered on that point must make a CON saving throw. A creature takes 2d6 fire damage on a failed save, or half as much damage on a successful one.

At Higher Levels. At higher levels roll an extra 1d6, 5th(3d6), 11th(4d6), 17th(5d6).
