X8K-S21: Tropicana
Strangely, Stargate's First Aid skill doesn't seem to do what you'd think it would, which is treat Vitality damage. It deals more with poison and disease and long term care. How is this FIRST Aid?
In the Revised system, it's treating those typical Vitality symptoms.... cuts, scrapes, bruises, sprains, etc. It's stopping bleeding, minimizing blunt force trauma, reducing shock, etc. It's the Wounds that represent broken bones, damaged organs, and more serious damage.
The target number for treating injury depends on the nature of the injury.
TN 10: minor injury (remember, there's still a penalty for a minor injury)
TN 15: serious injury
TN 20: major injury
TN 25: deadly injury
In Coleman's case, because his injury was caused by a previously unknown type of blaster weapon, the TN is 20.
A successful First Aid check restores 1d6 Vitality, plus one additional Vitality for every 5 points you succeed. Even if you don't succeed, as long as you have the skill, you restore 1 point (unless you fail by more than 10?).
Lizzie succeeded by 5, so she restores 6 points (max out of combat) plus 1. That puts Coleman back down into the LEVEL 1 FATIGUE category, with 1 Wound.
That's all First Aid will do. She still has her shiny new bioscanner.
