This black iron torc bears a ruby that seems to weep tears of blood.

A vampire torc allows you to heal your own wounds when you deal damage to an enemy. When you activate this torc, the next successful melee attack you make before the end of your turn also heals you of an amount of damage equal to half the damage your attack dealt. This ability functions equally well regardless of your creature type. If you don’t deal damage with a melee attack before the end of your turn, that activation of the torc is wasted.
This ability functions two times per day.

Prerequisites: Craft Wondrous Item, vampiric touch.
