“Rending ~ shadow magic. Using a focus (certain shapes are better as focuses, seems abstract but there is a reason. Staves and swords are good. Items associated with change (again, a sword) are better focuses as well). With these focuses, they Rend something touching their focus - shattering it irreparably. And I mean irreparably. If the shattered fragments are smelted down and forged, these fragments are significantly more difficult to Rend. Anyways, when a Render rends something, they begin to Rend their focus with each rending, until it is also broken permanently.
They can use their bodies as a focus, and their bodies are the best focus possible, but this is very very dangerous.”
