Weapon of Blood

The bloodknight binds his magic to his weapon and deals more damage with every attack for as long as the spell lasts. With every hit, blood is consumed. The metal of the weapon turns red, becoming inseparable with his wielder. Any other permanent enchantments on the weapon are enchanted to deal more damage during the spell.
