Ember Blast

A blast of glowing embers flies from your hands. Each creature within range must make a Dexterity saving throw or take 1d4 fire damage and be set on fire, taking an additional 1d4 fire damage at the end of subsequent turns. At the beginning of each of its turns a creature can repeat the saving throw. On a success the spell ends on the target. A flammable object hit by this spell ignites if it isn’t being worn or carried.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
