Brave individuals who scurry from person to person working to keep their Allies fighting strong. Practitioners are practical healers, relying on their own crafting skill instead of divine or arcane magic. They are trained to an expert level of understanding of medical knowledge, learnt through hours of study and practice.

Treatments. You learn 3 treatments of your choice, which are detailed under “Treatments” below. You can only use one treatment on your turn. You learn an additional treatment of your choice at 9th, 13th, and 17th level. Each time you learn new treatments, you can also replace one treatment you know with a different one.
