Certain types of creatures can equip (and drop) their own special items, along with standard items. These items can be of normal, magic or rare quality.
Monster Infrequents (MI) are rare variants of these items. They have a special name and art, and come with additional stats in addition to random affixes.
Some MIs are "unique" in the sense that they have no base item type, while others do; for example Murderer's Spaulders can drop as a normal, magic or rare item or as the rare Murderer's Epaulets Monster Infrequent item.
Shields and Off-HandsEdit
Some Monster Infrequents are used in blueprints for crafting other items. They can thus be worth stashing, even if they have unfavourable affixes or are otherwise of no use to a character. A list of MIs used and the items they create is shown below.
