When the result of one chart leads to a random roll on another chart.
Example
High Briars Encounter Chart might have a result of "Men A" and there is a sub-table of Men A that has a result of "Special NPC" that leads to a sub-chart of powerful NPCs, that means the first roll 'scattered' twice
> Early on the second day at sea there was a random encounter. It came up pirates and a scatter check meant they were being attacked by the Ravager.
