Dreamscarred Press makes a wide variety of classes using different subsystems of rules. The classes here use either psionics or akashic magic.

Akashic Magic

Akasha is an ancient form of magic whose use predates most forms of spellcasting known to the mortal world. Long before wizards began unraveling the secrets of the cosmos and codifying them into arcane formulae, and even before dragons, demons and other beings of magic began mingling their blood with lesser species, wise mystics and abstruse visionaries bound the raw magical essence known as akasha into crude physical forms and bent its might to their enigmatic purposes.

Akasha is a somewhat simplistic form of magic, generated by mixing life energy, called essence, with the small amounts of arcane magic that suffuse all things and shaping them into rough physical forms. These crude magical constructs are sustained by attaching them to points in the body that naturally conduct energy, called chakra. While modern spellcasters scoff at wielders of akasha as crude and unrefined amateurs, non-traditionalists still practice the ancient arts of shaping akasha - known as veilweaving - and trust implicitly in its power and reliability.

Path of War

To put it simply, the Path of War is a new way to look at martial combat. At its basic roots, the Path of War allows for martially-inclined characters to harness new abilities to aid them in combat. These new abilities are known as maneuvers, a specific technique that allows a martial disciple to enact a powerful attack, erect a defense against an attack, or improve his overall fighting ability or the abilities of others. By initiating these in combat, the martial disciple has a powerful edge that can even rival the powers of the spellcasters of the world.

Psionics

The innate power of the mind is present within all creatures. But it is those who choose to take levels in psionic classes who can unlock and develop this immense power contained within. This mental energy exists in many forms: Intelligence, Wisdom, and Charisma are direct links to the conscious mind, but the physical abilities: Strength, Dexterity, and Constitution, are also factors. Each of these component pieces is like a single facet of a greater whole.

Psionic characters do not simply tap into the power of the mind, but the power of the mind and the body together. The psionic classes utilize the totality of consciousness to transform thoughts, ideas, and dreams into the real world.
