Legendary - Diablo Wiki

Legendary (AKA "leg") items are the (potentially) highest quality items in Diablo 3 and Reaper of Souls. Legendary items are orange in color and announce themselves when dropped by 1) creating a loud *clang* sound effect, 2) sending up a beam of orange or green light, and 3) creating a star or asterisk icon on the minimap. Set Items are another type of legendary item and act just the same, except their beam coloration is green and they appear as an asterisk * on the minimap.
