Toxicity

You touch a willing creature, imbuing it with a resilience to toxins and coating it in a layer of noxious poison. For the spell’s duration, the target is considered immune to poison damage as well as the poisoned condition. Moreover, if a creature touches the target or hits it with an attack while within 5 feet of it, the creature takes 2d6 poison damage. A creature can only take this damage once per turn.
