Arcane word: Burn

Calling out it's name you invoke the eldritch power of flame to create a pillar of fire. Choose a point of origin within range to summon the flames and each creature in a 10-foot Radius of the origin must make a Dexterity saving throw. A creature takes 3d6 fire damage on a failed save, or half as much damage on a successful one.

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

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
