Burrowing Salamanders

4th-Level Evocation Spell (Druid, Sorcerer, Warlock, Wizard)

Casting Time: Action
Range: 60 feet
Components: S
Duration: Instantaneous

You send intense burrowing tendrils of flame into the ground.

Choose up to eight 5-foot squares at the far edge of a 60-foot cone originating from you. From each chosen square, a 40-foot-tall, 5-foot-wide column of fire erupts straight upward.

Each creature in a chosen square or in a column above it must make a Dexterity saving throw. On a failed save, a creature takes 7d10 fire damage; on a successful save, it takes half as much damage.

The fire ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels: The damage increases by 1d10 for each spell slot level above 4.
