Multiple characters can cooperate on the same downtime task. If it's a simple task that requires just one check, such as a party
Subsisting as they await rescue on a wild planet in the
Vast, one character rolls the necessary check while everyone else Aids that character. If it's a complex task, assume all of them are working on different parts of it at one time, so all their efforts count toward its completion. For example, a party might collaborate to build a starship, with one character drawing up blueprints, one scavenging for parts in junkyards, and the other working on the ship's computer systems.
