In my current campaign (in which I am a player) we are considering switching over to the Gritty Realism rest variant in the DMG so that the party would have to expend more resources between resting. The variant says:
This variant uses a short rest of 8 hours and a long rest of 7 days.
But we are confused at how this variant interacts with the normal rules for resting.
A normal long rest has this description:
A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps for at least 6 hours and performs no more than 2 hours of light activity, such as reading, talking, eating, or standing watch. If the rest is interrupted by a period of strenuous activity - at least 1 hour of walking, fighting, casting spells, or similar adventuring activity - the characters must begin the rest again to gain any benefit from it.
How do these rules transfer over to the variant? Is it true that you must spend 7 full days only in a single long rest and that you may not perform more than 2 hours of light activities over the entire 7 day (168 hour) period? It seems like over 7 days you could easily spend at least 2 hours eating and talking.
Would the long rest be invalidated if they take are interrupted by a single hour of strenuous activity over the entire 7 days? Even for a "gritty" variant that seems really extreme.
How are the activity limitations supposed to work in this variant?
