9.60 Spiritlore

Gifted with the power to pierce the layers of reality and commune with the
Spirit Realm, members of the Shaman class have access to wells of power thought
long-lost. 

Upon entering a trance, practitioners of Spiritlore may bind the spirits of one
or more ancient spirits to them, augmenting the Shaman's already impressive
arsenal of abilities with new features. Additionally, one may choose to further
attune oneself with a particular spirit and unlock even greater powers. The
most skilled practitioners are even rumoured to be able to attune themselves
with multiple spirits, or even of being able to sever their spirit from their
body and traverse incorporeally.
