Legendary Items are a type of item in Diablo Immortal, Diablo III, and Diablo IV that are similar in rarity to Unique Items in Diablo II. On many occasions, items of that caliber are also referred to as Legendary Items, or “Legendaries” (often abbreviated to “legos” or “legs”, not to be confused with leg-slot pants). They are among the most powerful and rare items in Diablo III.
Legendary Items return in Diablo Immortal. They change the player’s abilities.
Legendaries can be obtained through bounties, and the first Horadric Bestiary quest completed each day will grant a Legendary.
Legendary Items, unlike Rare Items, can have affixes that are normally not permitted on that type of item (for example, Increased Movement Speed on Chest Armor). Many of them have re-rollable or non-re-rollable affixes that are unique to that item (for instance, Azurewrath damages and periodically knocks away Demon and Undead enemies in close proximity of the bearer). Normal affixes on Legendary Items will roll significantly higher (and sometimes extremely high even when compared to other Legendary Items) and amount to more than those on regular items of similar levels. However, some Legendary Items are more than just glorified “Rares” with no unique stats or affixes. Over time, such Legendaries are replaced, gaining new names, descriptions, and properties, while older variants become Legacy.
Legendary Affixes on items are orange, with numbers that may roll in some interval (if any) highlighted in blue. Example (Winter Flurry):
Because orange affixes are always Secondary, they do not compete with an item’s Primary attributes. The majority of these affixes can be extracted using Kanai’s Cube.
To some extent, all legendary items dropped since patch 2.0 are account bound. The item will be tradeable for the next two hours of gameplay to any player who was in the same game when it was dropped. The item will be permanently bound to the player’s account after two hours of gameplay. Enchanted legendary items immediately become account bound.
As of patch 2.0, a Legendary item can drop at any level equal to or higher than its minimum level, with stats corrected accordingly. Craftable Legendary items may have two recipes (normal and max-level), each of which must be obtained separately. All items with a minimum level of 61 or higher require access to Reaper of Souls, though players can trade them to classic players if these items roll an affix that lowers the level requirements.
Set Items are essentially Legendary Items that come with additional bonuses for wearing more than one piece of the same set. Set Items, on the other hand, rarely have unique affixes.
All Legendary Rings and One-Handed Weapons are Unique-Equipped, which means that a character can only equip one of each type at a time, and even if the player finds two Stone of Jordan Rings, the character can only have one equipped. The only exception is that a character can still equip a pre-loot 2.0 version of the same item alongside a post-loot 2.0 version of the same item. This restriction was implemented to prevent characters from becoming too powerful; for example, a Barbarian dual-wielding two Thunderfury Swords would cause massive Lightning Damage wherever the player went, especially if he or she was a fast-hitting character. The same rule applies to the Kanai’s Cube “Powers Collection”.
Legendary Gems and Legendary Potions, in addition to Legendary Equipment, can be found in-game.
Legendaries are dropped by monsters, chests, and destructibles. They are not available in stores (except for Kadala’s gambling establishment). Some can only be obtained through crafting, and only after finding/purchasing the corresponding jeweler or blacksmith plan. Some legendaries (typically those with a minimum level of 70) can only be found in Torment, while others can only be found in Horadric Caches, and only if the cache was obtained from a specific Act. Horadric Caches do not contain Torment-exclusive legendaries.
When a legendary is discovered, it is unidentified. The player can identify it by right-clicking on it. If the player has several unidentified legendaries, it may be faster to travel to town and use the Book of Cain. The item’s stats are created when it is spawned, not when it is identified. It can have between six and seven magical properties, but rarely more.
When a character level 1–59 kills an act boss for the first time, at least one legendary item is guaranteed to drop. They can choose to “Reset Quests” once the game is completed with that character. This will once again guarantee one legendary item for the first kill of each act boss. Only Malthael will drop a guaranteed legendary item when a character reaches level 60 or higher. If the player does not have Reaper of Souls, this guaranteed drop is transferred to Diablo.
Each level of Torment difficulty increases the chance of a legendary dropping by 1.15N, where N is the level of Torment.
 Nephalem Rifts also increase the drop rate of legendaries, stacking multiplicatively with other modifiers.
Diablo III’s pre-expansion patch also adds a bonus to the legendary drop chance for players who have not found a legendary in a long time. This was designed for the unluckiest of players; without it, they might have been unable to complete their quest in a timely manner, even on lower difficulty settings. This bonus requires the player to spend time killing monsters, but it increases over time in an attempt to provide all players with at least some legendaries. The bonus is reset when a genuine legendary item, rather than plans or material, is dropped for that player. The bonus is even reset if the player is not near it when it drops, such as when the player is in town selling items while another player in their party is out killing monsters.
Two items were thrown together. It is a rare occurrence. Take notice of the minimap icons.
Each Legendary item makes a distinct sound and displays a star icon on the minimap upon dropping. Each item will also be highlighted with a pillar of bright light, making it difficult to overlook.
