The martial power source represents the sheer power of physical strength and willpower contained within the mortal races. Martial abilities are not magic in the traditional sense, although some of its practitioners are able to do feats of prowess well beyond the capabilities of ordinary mortals. Martial abilities are called exploits.
Classes that draw power from the martial power source are:
- Barbarian (berserker subclass only, which is also Primal)
- Bard (skald subclass only, which is also Arcane)
- Ranger (also Primal)
Martial classes and powers were introduced in the Player's Handbook.
