Shadowmancer Assassin

The Shadow Weave is a powerful force that could rival the Arcane Weave sown by Mystra. However, Shar's creation is shunned and forbidden by most civilization. But deep in the underworld, where the shunned gather and nothing is forbidden there are still those who weave the magic of shadows. Their powers are often strange and mysterious, seeming to violate the normal rules of magic, but to these practitioners the "rules" are artificial shackles on the minds and skills of arcanists.

The Shadowmancer Assassin is one such practitioner of the Shadow Weave. They are elite assassins using their mastery of shadow magic to leap from shadow to shadow faster than the eye can see, and weaving weapons from the shadows themselves to eliminate their targets. Nearly impossible to restrain, and even harder to disarm these assassins are among the most feared across the land.
