Ember Burst

You generate a small, unstable ember that lingers for a brief moment before violently igniting. At the start of your next turn, the ember explodes in a 5-foot radius around you. Each creature in the area must make a Dexterity saving throw, taking 1d8 fire damage on a failure or half as much on a success. Flammable objects that aren’t being worn or carried ignite. The explosion occurs even if you are incapacitated, though you can dismiss the effect as a free action before it triggers.
