Set Armors make a return in Diablo 3, and like in its predecessor they have essential bonuses when worn.
The game will follow the same Sets trend as it did in Diablo II: a few set items shall be generic, whereas some will be entirely class-specific.
But for those who aren’t acquainted to the concept of Set Items and Armors, here’s a thing or two for you to know if you find one:
Set Items and Armors in the world of Diablo are unique items which maintain their specifications (such as strength, durability, armor, add-on effects etc.) irrespective of when or where they are found.
This is not the case with other item types, except for Legendary Items. Thus, Legendary Items and Set Items are categorized in as Unique Items.
Set Items come in sets. For example, the Natalya’s Wrath set consists of five parts: Natalya’s Gaze, Natalya’s Mark, Natalya’s Redemption, Natalya’s Shadow, and Natalya’s Soul.
When two of the five parts are worn simultaneously, an added specific bonus attribute is given to your character. Wearing more than two will give increased magnitude of the bonus, while wearing all five will give you massive bonus effects.
