Travel Time Calculation: The captain makes 3 Occupation (Sailor) checks, if he passes all three checks he makes the voyage in the time indicated above. If he fails once, add 1d6 days. If he fails twice double the time. If he fails three times, he takes triple the time. From December 1st through March 31, all rolls are made at disadvantage.
Mishap: for each voyage roll 1d20, if the result is a “1” some serious mishaps occurs–sea monsters, terrible storm, etc., that must be adjudicated by the DM.
