Cross Combustion

Choose a point within range. 4 lines that are 30 Ft long and 5 Ft wide sprout from that point in a "+" shape. Each creature inside one of the lines' area must make a Dexterity saving throw. A target takes 5d8 fire damage on a failed save, or half as much damage on a successful one.

The lines stop if they meet a wall or other solid object that wouldn't catch on fire, such as a stone wall or a marble statue.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
