Agonizing Itch

You enchant one creature within range, and a giant red welt grows on their body. Every turn until the spell ends, they must make a Constitution and Wisdom save. If they fail either, they must use their action to scratch the itch, taking 1d4 slashing the first time they scratch it, then 1d6 the second time, with a max of 1d8. If they are within 5ft of a ally for at least 2 rounds, the ally also gains a giant red welt on their body with the same effects except the max die is 1d6.
