This painted brass bottle weighs 1 pound. When you use an action to remove the stopper, a cloud of thick smoke flows out of the bottle. At the end of your turn, the smoke disappears with a flash of harmless fire, and an efreeti appears in an unoccupied space within 30 feet of you. The first time the bottle is opened, the GM rolls to determine what happens: 01-10: The efreeti attacks you. 11-90: The efreeti serves you for 1 hour, performing your commands. 91-100: The efreeti grants you three wishes.
