Grog is a the beverage of choice for all Player Pirates in Sea of Thieves. Every Tankard is filled with Grog by default, and can be replenished at sources such as Taverns, the Chest of a Thousand Grogs, or Grog Barrels on ships.
Players can drink Grog by using their Tankards. When a Tankard is emptied, it can be refilled at any Grog Barrel, Tavern or a Chest of a Thousand Grogs. As more Grog is consumed, the player will become increasingly more drunk. The effect can last up to a couple of minutes.
Drunk players will experience various effects. Their vision will become slight blurred and their movements will become unstable, swaying left and right even without any player input. This also affects how a player interacts with items. Handling Equipment, Sails, the Wheel, the Harpoon, Cannons or a Rowboat all become more difficult as the player's actions become involuntary. Any drunk player who plays an Instrument will play severely off-tune.
Drinking too much will make players sick, after which they will start vomiting. Every time a player vomits, their vision becomes even more blurry. Any players hit by vomit will have their screen filled with the green liquid and potentially become sick themselves.
Players can use the Bucket to catch their own vomit and throw it from the bucket as they would water. This can be used to hinder the vision of other players and can be an effective tool in combat. Vomit can also be used to douse Fire.
