Envenom

You coat your weapon with venom. you make one attack with the weapon used in the spell's casting against the target. On a hit, the target takes 2d6 Poison damage. The Toxin on the blade forces the target to make a Constitution saving throw(8 + spellcasting ability modifier + your proficiency bonus). On a failed save, the target has the Poisoned condition for 1 minute. At the end of each of its turns, the Poisoned target repeats the save, ending the effect on itself on a success. If the Target is immune or resistance to poison it has no effect.

Cantrip Upgrade. The damage increases by 2d6 when you reach levels 5 (4d6), 11 (6d6), and 17 (8d6).
