Body represents a Contractor's physical fortitude and overall health. Body is depleted by being Injured, which can lead to an increased Penalty or death. Body is rolled when a Contractor's physical endurance is tested, such as when resisting poisons, diseases, or air deprivation.
A Contractor's rating in Body is equal to 5 + (Brawn / 2, rounded up). A moderately fit human will thus have a Body rating of 7, while hulking brutes will have 8 Body and weaklings will have 6 Body.
If you are using The Contract's Online Character Sheets, your Contractor's Body rating is automatically calculated from your Attributes and displayed on the sheet.
The overall effect of a Contractor's current Injuries is summarized by depleting their Body. The amount of Body a Character has remaining is equal to the Severity of their worst Injury plus the number of other Injuries they have. A Contractor's Body will heal over time, depending on the Severity of their Injuries, but particularly brutal injuries will leave Battle Scars that do not heal.
Here is an example: if Nerise has 3 Brawn, she has a Body score of 7 (5 + Brawn / 2, rounded up). She falls down the stairs and breaks her ankle (a Severity 2 Injury). She now has 5 Body remaining (7 - 2). If she is then stabbed in the chest by a giant hornet's stinger (a Severity 4 Injury), she has 2 Body remaining (7 - 4 [most severe injury] - 1 [number of other injuries]). If she survives the game, her injuries will eventually heal, but the wound from the giant stinger will leave a Battle Scar which has lasting consequences, possibly chronic pain or difficulty breathing.
The Website's Character sheets have an easy-to-use Injury tracker that calculates these values for you.
If a Character's Body is fully depleted, they are Incapacitated - they cannot move on their own, automatically fail any Actions that requires a roll, cannot activate any Powers, and can only speak at a whisper. If they are Injured beyond Incapacitated, they die. Death should be avoided if at all possible, as there is not generally any support for resurrection in The Contract.
When a Contractor's physical fortitude is tested, the GM may ask them to roll their rating in Body. The number of dice rolled in a Body roll is equal to the Character's permanent Body rating (5 + Brawn / 2, rounded up) but is reduced by their Penalty, as normal. Unless stated otherwise, the Difficulty is the standard 6.
