Unique items include those of Epic and Legendary rarity. These items are the rarest and most powerful items in Grim Dawn. Unique items have pre-determined stats, as opposed to the randomized affixes of Magical (yellow) and rare (green) items, and can sometimes come with active or passive Granted Skills.
Unique items can drop as loot anywhere from monsters or chests; one-shot chests in particular contain a guaranteed random Epic. Some can also be crafted after finding the appropriate blueprint. The Blacksmith Etram Fald will also craft random Legendary items for the appropriate cost.
Unique items may also form part of an Item Set.
