|“||This cursed spear will appear as a magical spear, however when a combat situation arises, the wielder will attack an enemy and Backbiter will attack the wielder. For every attack made, Backbiter will attack the foe and also the wielder. This is a powerful spear, but one must ask if it is worth it in the end. The only way that Backbiter can be removed is by a remove curse spell.||”|
