The Grandfather is a Unique Great Sword from Diablo I that is found randomly. It deals very nice Damage, and gives a boost to All Attributes and Life. In addition to these abilities, The Grandfather is One-Handed, unlike other Great Swords. Although the negligible to hit bonus makes the sword unsuitable for a non-rogue class on Hell difficulty, The Grandfather is still regarded by some players as the most powerful unique sword in Diablo I.
