Scorch

Even a single spark can start a wildfire.
You snap your fingers, attempting to light an unattended object within range on fire. If you target a flammable object, it immediately combusts in a gout of flame. Choose up to two creatures within 5 feet of the burning object. Each must make a Dexterity saving throw. If a creature fails, it takes 1d8 fire damage.

This spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
