When a ship to which you are [[Attuning to an Airship|Attuned]] travels for 24 hours or longer, you can perform a special on-hour ritual that allows the ship to travel faster. At the end of the hour, make a DC 15 [[Intelligence]] check using proficiency in [[Tools#Navigator's Tools|Navigator's Tools]]. On a success, the ship's movement speed increases by 50 percent for the next 24 hours.
