Manage Course
While starship autopilot systems are fairly efficient navigators, you can shave off a bit of travel time with skilled micromanagement of a ship’s course, taking advantage of opportunities provided by the ever-shifting nature of the Drift or fluctuations in microgravity in normal space.
Activity
As the pilot of a traveling starship, attempt a Piloting check to navigate with a DC equal to 10 higher than the DC for plotting the initial course. You can’t take 20 on this check.
Results
On a success, you reduce your total travel time by 6 hours. If you fail by 5 or more, you instead add 6 hours to the trip. If you fail by 10 or more, you also suffer more serious consequences as normal. You can’t reduce the total travel time below its normal minimum plus the number of days spent managing the course. For example, a trip to the Vast during which the Pilot spends 3 days successfully managing the course can’t be reduced below 8 days (5 minimum for the trip plus 3 days spent managing course). Only one creature can perform this activity for a given starship each day.
