|“|| Two Handed Sword +3: Harbinger
When the hero Trueblood destroyed the Harbinger, a demon gorging itself on the blood of peasant folk near Luskan, he bound its essence in the only vessel capable of holding it, his fabled sword, Deliverance. Though the evil creature was dominated by the will of the semi-sentient blade, it was not truly defeated, and it transformed the weapon from within. Now it acts much like any other enchanted weapon, but when it strikes, there is a small chance that a fireball erupts, a sign that the demon within still rages at its imprisonment. There is also a chance that any ogre it hits will be turned to stone. Whether this is an ability of the demon or a vestigial power of the original blade is not known.
