Cobra’s Breath

Your saliva changes into a potent venom that you then spray forth. Each creature in a 20-foot cone must make a Constitution saving throw. On a failed save, a creature takes 2d10 poison damage and is poisoned until the end of your next turn. On a successful save, it takes half as much damage and isn't poisoned by this spell.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
