Brew of Protection from Fey

Rare Potion

Fey Ward. The bright green liquid inside this bottle does not have any distinct smell, but it does have a very sweet taste reminiscent of green apple, that lingers in the mouth as long as the potion affects the drinker.
When you drink this potion, you are protected against Fey creatures. The protection grants several benefits. Fey creatures 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.
