Toxic Barrage

You create four rays of pure poison and hurl them at targets within range. You can hurl them at one target or several.
Make a ranged spell attack for each ray. On a hit, the target takes 3d6 poison damage. If a target is hit by one or more of these rays, it must make a Constitution saving throw. On a failed save, the target is poisoned for 1 minute. While poisoned in this way, the target can repeat the saving throw at the end of each of its turns. On a success, it is no longer poisoned.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you create one additional ray for each slot level above 5th.
