Monster Traits in Diablo III are special abilities that are added to Champion, Rare, Unique and Minion monsters. These traits appear beneath the name of the monster. The number of traits depends on that of your hero's level; to be specific, a Champion/Rare/Minion encountered at lv. 1-29 will have only one trait, those encountered at lv. 30-49 will have two traits, 50-59 will have three, and 60+ will have four traits possible. Unique monsters have one to four affixes regardless of their level. Some traits cannot appear on Champions / Rares at lower levels: for example, Arcane Enchanted only rolls at level 31 or later.
