Many have fell victim to the Ritual Blade's crimson edge. Both human and demonic blood soak the steel, giving it a unique power of a demonic, damaging aura. However, it must enter the bloodstream to do so. When one cuts him/herself with the Ritual Knife, increased damage is granted with all weapons for 15 seconds. The Knife never goes away, but the damage goes both ways: While one can deal more damage, s/he takes more as well.

(Increased damage at the cost of pain and more damage taken. Reusable.)
