The Complete Spacefarer's Handbook[]
The character has learned the art of navigating through wildspace, avoiding hazards and using planetary motion to improve speed over long journeys. A successful proficiency check allows the character's spelljamming vessel to arrive at its wildspace destination 10% faster than normal. Thus, if it would take 10 days to make the trip normally, the character can steer a course that will take only nine days. An unsuccessful proficiency check indicates that no time is saved; on a roll of 20, travel time increases by 20%.
