Virelian Scorcher

You unleash a rushing line of blooming vines and volatile spores. Each creature in a 30-foot-long, 5-foot-wide line must make a Dexterity saving throw. A creature takes 3d8 poison damage on a failed save, or half as much damage on a successful one.

The vines left behind wither into lingering toxin. The line becomes difficult terrain until the start of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
