You burn the kindling in your hands and blow it onto a creature in range. The creature must make a Constitution saving throw. On a failure, the creature takes 1d8 fire damage and at the start of the creatures next turn it takes 1d6 fire damage. On a success the creature takes half of the initial damage and no damage at the start of its next turn.

At higher levels. When you cast this spell using a spell slot of 2nd level or higher, the initial damage increases by 1d8 for every slot above 1st, and the number of turns the creature takes the second damage is equal to the slot level expended.
