Apologies if this has already been asked (and extra apologies if I am being dense in not understanding it). When a whisper carries out a ritual I get that it takes 1 downtime action and they take stress as agreed with Ritual creation. But it then says the ritual takes time to cast (usually at least an hour). It also says the duration of the casting can be extended to reduce the stress. What I done understand is if this duration is supposed to occur in game time, and if so is the stress taken in game time. Or is the duration occuring abstractly in downtime, and the stress taken in downtime (in which case how is the duration relevant?)
Or do you prepare the ritual in downtime (using a downtime action) then cast is game (which takes the duration) in which case when is the stress taken?
Thanks for any suggestions
