Characters with the Trauma skill can operate on wounded characters in order to help them to recover from wounds. In the post-apocalyptic world of Avoss, surgery can be just as dangerous as violence, but it is a necessary danger for those who wish to stay alive. Surgery is performed as follows;
For every point of damage a character has suffered and wishes to have healed the surgery duration is extended by 5 minutes.
After every fifteen minutes of surgery the surgeon is required to roll a twelve sided dice and resolve the roll based on the ‘surgical complications’ table. This may extend the surgery time or cause additional damage.
For every hitpoint healed, a member of the surgical team has to spend a point of cool. This occurs during the surgery (every five minutes) but hitpoints are only regained at the end of surgery.
If the operation is taking place in an unclean area or with unclean tools, risks are more frequent. If either circumstance is present, roll for complications every 10 minutes. If both are present, roll every 5 minutes.
It is important to note that if a character is bleeding out during surgery they must be have their bleedout stalled through the entire surgery.
Surgery requires at least 1 person with the Specialist Trauma skill or 2 with the General Trauma skill to attempt.
