Mage: The Gun Quarter
When Samuel made mention of the price, Art balked until Rory Cooper stepped in with payment.
Art imbued the blade with a bloody resonance and gave it an enchantment allows the blade to heal the wounds it inflicts. This is particularly useful for quick recovery after blood-letting.
Art gifted the blade to Rory to aid him in his extended-rituals and blood magic. Rory was surprised by the gift and accepted it graciously.
