Ironically, the Grandfather sword does not have any actual unique power. Instead, it rolls with significantly higher affix values compared to other items. It comes Diablo 4 Items with a flat bump to max Life, a percentage bonus to all damage, a boost to all stats, and a modifier that makes it ignores durability loss. The Grandfather's main draw, however, is its insanely high Critical Strike Damage modifier.
So far, only Barbarians and Necromancers can wield Two-Handed Swords in Diablo 4. Since drop tables are adjusted to match whichever character players are currently using, it's best to farm for the Grandfather using either of these classes. Running dungeons with a full party also maximizes the odds of getting this Unique since everybody gets their own instanced loot.
One of the main draws for Diablo 4 players is the potential of finding rare and powerful gear while exploring Sanctuary and tackling its dungeons. Of all the possible loot drops in the game, unique quality gear is the rarest, and among this category there are six super rare items considered to be the rarest of the rare. Prior to Diablo 4 lead class designer Adam Jackson revealing these six items and confirming their existence on Twitter, many players thought they were a myth due to how rare they were.
After this revelation, Diablo 4 players were eager to uncover these "chase" items in-game, as they became the most highly sought-after items with many players wanting to be the first to discover them. These unique items only drop from enemies at level 85+, which are best farmed from Tier 31+ Nightmare Dungeons on World Tier 4, meaning players won't even have the chance to find them until very late in the game. In recent weeks, all six of these items have been discovered in-game, and thus, the hunt for Diablo 4's most elusive items has ended.

Harlequin Crest (Shako)
Perhaps the most infamous super rare unique, the Harlequin Crest, also referred to as the Shako in reference to Diablo 2, was actually the first of these items to be discovered. The Shako was found in Diablo 4 only a few days after the game's launch by a member of Korean Diablo streamer drlee_kor's community. The discovery was later confirmed on Twitter by Diablo 4's global community director Adam Fletcher who assured fans that the Harlequin Crest had indeed been found in-game.
What makes the Harlequin Crest so desirable aside from just its rarity is the fantastic affixes it comes with that can really power up a build in the late game. It grants the wearer 1025 Armor, +732-1359 Max Life, +4.4-10.0 percent Cooldown Reduction, +5.0-12.0 percent Resource Generation, and +20-28 All Stats. Additionally, its unique affix gives players an additional +10.0-20.0 percent Damage Reduction as well as a whopping +4 to all Skills, making it an extremely versatile helm for any build.
Andariel's Visage
Despite the discovery of the Shako coming shortly after the launch of Diablo 4, the rest of these ultra-rare uniques remained undiscovered until quite recently. The next to be found was the helm Andariel's Visage, which was found shortly after the confirmation by Adam Jackson that the items do indeed exist in-game. Diablo 4 player Lithie was the one who made this discovery and showed it off during Polish streamer NadinWins' broadcast to a crowd of astonished viewers.
Like the Shako, Andariel's Visage is another near universally useful helm with a series of affixes intended to greatly increase the survivability of the wearer. Aside from giving the player 1025 Armor, its affixes include 4.4-10.0 percent Attack Speed, +24.5-45.5 percent Poison resistance, +10-18 All Stats, and +1.3-2.0 percent Life Steal. The unique affix on Andariel's Visage gives the wearer a cheap Diablo IV Gold Lucky Hit chance to trigger Poison Nova, dealing 10,077 Poison damage over 5 seconds which can easily sap the life of enemies and restore the wearer's health with its Life Steal affix.
