Heal is used for negating poisons and treating minor injuries. It is done on either the field of battle in the midst of combat or during a period of rest.
First Aid: Stabilize a character (bring them to 0 HP) and stop them from bleeding out, and brings them to 1 HP.
Long-Term Care: The target of the healing recovers 4 HP per their level.
Treat Deadly Wounds: Negates bleed, and the target of the healing recovers 5 HP.
This uses Magic or Smarts as an ability.
The following are expanded uses for characters. These checks are considerably more difficult, and usually only able to be completed by the most dedicated practitioners.
