Black Blade

Feats

At 1st level, the bladebound magus gains a powerful sentient scimitar called a black blade and can communicate with it telepathically. As a swift action, the magus can manifest the black blade in his hand. The black blade gains a +1 enhancement bonus. At 5th level and every 4 levels thereafter, this bonus increases by +1 (to a maximum of +5 at 17th level).
