What is Incarnum?
Incarnum is a source of power, like arcane or divine magic but distinct from all others. Incarnum is the energy and matter of souls, the souls of the dead, those living, and those not yet born. There are different ways of interacting with this power, but the most common is to shape it into other forms, selecting the souls to shape as you do, to create semi-permanent objects that grant a variety of effects. While members of any class can use incarnum with training, there are three classes which use it as the base of their powers. First, the Incarnate, unwavering champions of a single alignment, who shape the souls of extraplanar beings and great heroes into a myriad of forms. Each incarnate is vastly from the next, and incarnates of different alignments are so different as to be almost different classes. Second, the Soulborn, awesome combatants of the extreme alignments, who shape the souls of mortals into combat focused soulmelds. Their power changes their body, making them immune to certain effects depending on their cause. Finally, the Totemist, stalwart defenders of nature who shape the souls of powerful beasts into soulmelds to use the power of those creatures. They have access to a special bind that dramatically increases the power of a single soulmeld.
