Red blood erupts along the weapons blade, bludgeon, or point. The blood drips to splatter in thick, viscous drops on the ground.

This spell infuses the weapon touched with baleful energy. The next time this weapon strikes a living creature, blade of blood discharges. The spell deals an extra 1d6 points of damage against the target of the attack.

The weapon loses this property if the wielder drops it or otherwise loses contact with it.
