Travelling on Station Five isn’t as straight forward as slapping on autopilot and going into stasis. Space is hostile, and the weather out here supremely hostile to life. While the Baron can handle empty space with relative ease, anything else requires the active assistance of the crew. While there is an adequate crew to keep Station 5 functional, the expertise of the senior officers ensures that every station runs at peak efficiency.

Each day the DM rolls 2d6 to determine what the weather is like or chooses it, which affects the collective DC required for checks made by the party. On a successful roll, the party is able to march at their chosen pace (PHB p181).

To succeed on a roll, the majority of party members must succeed on their skill check. Station 5 is a complex machine, and nearly every kind of tool proficiency if helpful to its function and maintenance. Certain background or class features may also grant advantage to travel checks, or even allow individuals to succeed at them automatically if the conditions are right.

Travelling at a slow pace grants advantage on the travel check, whereas travelling at a fast pace inflicts disadvantage.

Once a player rolls, they can choose to roll again to aim for a better result. If they do so they gain 1 point of exhaustion the following day. A person can re-roll multiple times per day with the caveat that cannot do so if it would kill them.

A person may choose to rest on a day instead of work. In that case they are able to recover points of exhaustion.

One day spent working at a particular station with those tools also counts as a day towards any downtime project that also uses those tools. This can include the Training activity, where the character learns how to use those tools with proficiency by practicing over the course of travel. Alternatively, a character can use travel-time to do other downtime activities that do not directly contribute to CP’s function, such as performing religious rites.

The typical rules for crafting items require that you pay half the cost in materials to create something of a given value. However, art and treasure are an exception, given that their value is typically embodied in the aesthetic quality imbued through the vision of the creator. When creating art (which might include furniture, jewellery, delicate beverages, or fashionable clothes), you only need to expend 20% of the items target price.

Characters who spend downtime resting / recuperating also gain 1HD of temp hitpoints per workweek, maximum their CON modifier.
