The Grog Barrel or keg is a stationary Item which can be found on all ships or outposts. They can be located in any Tavern where you can get you Tankard filled for free. Drinking a full Tankard of Grog causes the player's visuals to become distorted, and their movement may become difficult to control. Drinking multiple full Tankards of Grog causes a player to stumble around wildly, hear drunken bar chatter and distorted music, and vomit.
Please be responsible while drinking.
