Resting and Recuperating

RESTING

To rest, a character must consume a ration and sleep for 8 hours. Sleep can be broken up for light and routine tasks, such as taking a turn on watch.

Interruption. Each stressful interruption of rest (including combat) requires an affected character to make a DC 12 Constitution check. Additionally the check increases by 1 for each interruption beyond the first.

On a failure, the character consumes a ration but gains no benefit from resting.

Success. A character who successfully rests regains hit points amounting to half their hit die (rounded down) plus their constitution modifier (if possitive). Additionally the recovers one point of stat damage that was not permanent.

Additionally, some talents, spells, or items regain their ability to be used after a successful rest.

Characters who are unable to rest are fagiued and suffer a negative 1 penalty to all rolls the following day. This penalty is cumulative for up to five days (-5) and beyond that the character is incapacitated.

RECUPERATING

Recuperating is the time that you spend in the warm embrace of civilization. This could be resting at an inn, castle, or even in your own bed. These breaks are very necessary as character become worn down traversing the wilderness and roads and can be weakened or, in extreme cases, die.
A character may travel the wilds for a number of days equal to their constituion score. After that time they must make a constituion save each day or premanently lose 1 point of constitution until such time as they are able to take time to recuperate. Note that Ranger are the exception to this rule as they get double their constitution in days sand have advantage on the save to stave off the debilitating effects.
Should a character reach zero constituion then he has died of exposure, malnutrion, and illness.

Characters resting comfortable in town recover an amount of contitution damage per day depending on their accomodations (1 per day for basic, 2 for comfortable, and 3 for lavish). Regardless of their comfort level they also reset their wilderness counter after 6 days (one week) in civilization.

The Winter

The winter is a time for hearth and home, not campaigning, or so common wisdom says. Time traveling in the winter counts as double and all checks to stave off permanent constituion loss are at disadvantage.
