Hogwash
Potion, uncommon
A waterskin filled with a pig’s used bath water. As an action you can douse yourself with this murky brine, granting you pig powers for 1 hour. You gain 1d10 temporary hit points, advantage on Constitution saving throws, and advantage on Wisdom (Survival) checks to forage for food for the duration.
You exude a rancid odor while coated in this liquid, giving you disadvantage on Charisma (Persuasion) checks. This negative side effect lasts until you bathe.
Brewed by the all-powerful pig wizard Maurice le Boueux for his followers who desire to become more piglike. His raucous foraging parties gained widespread renown for their yield of high quality truffles as well as their unbearable stench. Although many outsiders claim Maurice is just an ordinary pig, anyone who douses themselves in his bathwater cannot deny its transformative effects!
Errata 4/9/2023- Reduced rarity from Very Rare to Uncommon, lowered temporary HP from 2d10 to 1d10, replaced +2 to Con saves with advantage on Con saves.
