Lava Eruption

4th-level transmutation (Druid,Wizard)


  • Casting Time: 1 action
  • Range: 90 feet
  • Components: V, S, M (a bottle carved of obsidian)
  • Duration: Concentration, 1 minute

Choose a point you can see on the ground within range. A fountain of liquid hot magma erupts in a 20-foot sphere centered on that point. For the duration, the area of the spell (including all portions of that area, above the ground or beneath it) becomes difficult terrain, and the lava ignites flammable objects in the area that aren't being worn or carried. A creature takes 3d6 bludgeoning damage and 3d6 fire damage when it enters the spell's area for the first time on a turn or starts its turn there. After the spell ends, the area of the spell remains difficult terrain until it is cleared. Each 5-foot- square portion of the area requires at least 1 minute to clear by hand. Firenewts or earth-based or fire-based elemental creatures (such as gargoyles or salamanders) do not take damage from this spell. Instead, such a creature is healed, regaining hit points equal to half the fire damage inflicted. Only firenewts or creatures of the elemental type can benefit from this effect.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the bludgeoning damage and fire damage each increase by 1d6 for each level above 4th.
