Types of weave

Pure Arcana
Use of the purest form of magic, either tapping into it or studying it thoroughly. Used by Sorcerers and Wizards.

Twisted Arcana
By manipulating the weave trough emotion and will, Bards, Warlocks and Blood Hunters gain the ability to cast magic.

Wild Arcana
A form of magic between arcane and primordial, believed to be the predecessor of the modern pure arcana. It can be seen in the corners of the world, where standard books and scrolls have yet to see the light of day.

Divine
Wielded by Clerics and Paladins, it is the Gods' will that gives them power to wield magic.

Nature
Primordial in nature, wielded by Rangers and Druids, harnesses the power of the Elements, spirits of Earth and the like. The cleanest form of shifting the weave, and even KI can be seen as a form of nature magic.
