Super Rares are a term coined by the community for select Rare Elites in Dragonflight, which drop loot that scales up to Item Level 385. Here’s a list and a map with exact locations of the mobs.
Super Rares can be defeated each day for loot. There’s a chance to receive loot you cannot equip. Blizzard has posted maps with the exact locations of Super Rares on Twitter.
