Only three effects can be equipped this way – one for weapons/off-hands, one for armor, and one for jewelry.Once an effect is stored, a character can equip the effect in the menu, so it will be active no matter what equipment they have.

Extracted Legendaries are stored in the Cube.Materials required: 1 Khanduran Rune, 1 Caldeum Nightshade, 1 Arreat War Tapestry, 1 Corrupted Angel Flesh, 1 Westmarch Holy Water, 5 Death’s Breaths.Once you have unlocked Kanai’s Cube, all of its functions will be immediately available. Once unlocked, it can be found in any town. Once inside, go to the end of the second level and you will unlock Kanai’s Cube.It will be located in the Ruins of Sescheron in Act 3 (at the top-right Waypoint of the map).Though, since enemies will scale with your level, it can be easier to get it while you’re low level. Once you do, it will be unlocked for all characters in the same game mode (Normal, Seasonal, or Hardcore). It is not available by default – you will have to find it first.

It has a multitude of uses, which includes letting your character gain extra equipment abilities, and reducing much of the RNG when getting the perfect gear for Greater Rift pushing. Kanai’s Cube is a very important tool for Diablo III’s end game, but it can also make the early game much easier.
