Downtime
Downtime is the time between sessions. Each player gets a single downtime activity each week. If the downtime is not used for anything else then it is instead used for a long rest. However you may decide to instead of taking a long rest take a downtime action which will give you some benefit by the beginning of the next session. This can also be done if you are going to miss one or more sessions you may have your character perform a downtime activity in exchange for that week's long rest. An activity only counts as a downtime action if it is an active activity that would take up most of the time between sessions. This means things like copying wizard spells or using tools would not count towards a downtime action. But patrolling sunholm, training, or watching over children would.
