Flux
Time flows erratically in a plane with the flux type. When a creature moves from a plane with this type to one without this type, roll 1d20. Groups that leave together share the same result.
17-20 For each day spent in the flux plane, 1 round passed on the plane with normal time.
13-16 For each day spent in the flux plane, 1 hour passed on the plane with normal time.
9-12 Time passed normally.
5-8 For each hour spent in the flux plane, 1 day passed on the plane with normal time.
1-4 For each round spent in the flux plane, 1 day passed on the plane with normal time.
