What about something like this
First Aid [Spiritual/Other 2]: You may touch another target and call 'First Aid' while role-playing binding
their wounds. You cannot use this skill while holding or using any weapons or packets. This will halt their
bleed-out count if they are bleeding. After one minute, you may call 'Stabilize' or
'Imbue Splinted by Medicine'.The 'Stabilize' effect stops a target's bleed-out count and makes them stable instead of unstable.
The 'Imbue
Splinted by Medicine' effect will give a character who is suffering from the "Maim" effect the trait "Splinted" which means that the Maimed limb will become usable until that character is struck again by a physical strike on that limb, or becomes unstable. Curing the Maimed limb (by magic or some other means) also removes the Splinted trait. The time it takes to perform this skill is doubled if you are using it on yourself. You must have at least one usable arm to perform this skill at all. Using this skill has
no Stamina cost, but the user may expend any number of Spiritual Stamina points to decrease the time it
takes by five seconds per Stamina point spent.
So we make Splinted a Trait (since those can change from game to game), and we have the First Aid'er Imbue that trait onto the person. Since it's up to the person giving a trait (Through Inflict or Imbue) to explain the trait through a card or through an IG method this leaves it up to the first aider to explain it to someone who doesn't know what it means yet.
Example:
Fighter: "Dammit, my leg, help me"
Mage: "Well I'm kind of tired right now, but I could put a splint on it."
Fighter: "Whatever, just get me walking again"
Mage leans over and performs first aid then says, "Imbue Splinted by Medicine"
Fighter: "What did you do to me?"
Mage: "Well it's kind of crude but I put a splint on it, just be careful the next time the leg gets struck it will be broken again, come back and see me in 5 minutes, so I can fix you up right"
Fighter: "Gee thanks a lot, I owe ya one"
