Brew of Protection from Fiends

Rare Potion

Fiend Ward. The red liquid inside this bottle does not have any distinct smell, but it does have a strong sulfur like taste to it that lingers in the mouth as long as the potion affects the drinker.
When you drink this potion, you are protected against Fiends. The protection grants several benefits. Fiends have disadvantage on attack rolls against you. You also can’t be charmed, frightened, or possessed by them. If you are already Charmed, Frightened, or Possessed by such a creature, you have advantage on any new saving throw against the relevant effect. These effects last for 10 minutes.
