Thunderbolt

You call a large bolt of lightning to strike a creature or object within range. The target must make a Dexterity save (DC 15). On a hit, the target takes 1d10+2 lightning damage. A flammable object hit by this spell ignites if it isn't being worn or carried.

This spell's damage increases by 1d10+1 when you reach the 5th level (2d10+3), 11th level (3d10+4), and 17th level (4d10+5).
