Venom Strike

You morph your finger into a venomous stinger, and strike at the enemy. Make a melee spell attack. On a hit, the target takes 3d6 poison damage and must make a Constitution saving throw. On a failure, it is poisoned for 1 minute.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage dealt increases by 1d6 for each slot above 2nd.
