The Mysteries and Challenges of Diablo 4

Two unique drops in Diablo 4, Harlequin Crest and The Grandfather, are so rare that players are unsure if they exist, but Blizzard has confirmed that they do. These items are supposed to be some of the rarest in the game and may only drop at World Tier 4 and level 100. The Grandfather increases critical strike damage and has higher properties than any other sword, while Harlequin Crest provides various bonuses such as increased max life and damage reduction. The rarity of these items adds to their mythological appeal, but it may be difficult for players to obtain them.
