Curse of Strahd
The Blood Spear
The Blood Spear was wielded by a barbarian leader who opposed Strahd. Like all others who did so, the barbarian leader died in ignominy. His corpse was buried on Yester Hill, but his sacred weapon called out to another.
The Blood Spear functions as a +2 glaive in the hands of its chosen wielder. Further, if the wielder kills a creature with the Blood Spear, the wielder gains 2d6 temporary hit points.
