Ember

You hurl a bright speck of fire that emits wisps of smoke at a creature or an object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6 Fire damage and starts burning. A flammable object hit by this spell starts burning if it isn’t being worn or carried.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6).
