Composed of a dark, dull metal, this weapon is cold to the touch. Indeed, it seems to absorb your body heat.
Whenever a bodyfeeder weapon you wield scores a successful critical hit against a living creature, you gain temporary hit points equal to half the damage dealt by the critical hit. These temporary hit points last for up to 1 minute and don’t stack with those from any other source, including additional critical hits with this weapon.
Prerequisites: Craft Magic Arms and Armor, vampiric touch or claws of the vampire (EPH 84).
Cost to Create: Varies.
