Brew of Protection from Elementals

Elemental Ward. The dark blue liquid inside this bottle does not have any distinct smell, but it does have a surprisingly minty fresh 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 Elemental creatures. The protection grants several benefits. Elemental 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.
