Affliction

You hex one creature within range, causing strikes against it to bite deeper until the spell ends. The target must make a Charisma saving throw. On a failed save, when an attack targeting the creature deals less than 8 damage, the creature takes 8 damage instead. The damage dealt is the same as the type caused by the attack.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the minimum amount of damage required to trigger the spell and the damage the target creature takes increase by 2 for each slot level above 2nd.
