Living Steel is a lair boss key you can get from Helltides and Undercity of Kurast in Diablo 4 (D4). Read on to learn more about how to get Living Steel, how to use it, and its general overview here!
List of Contents

The best way to get Living Steel is from any Tortured Gifts found in the Helltides, particularly from the Tortured Gift of Mysteries.

Using the Tribute of Titans in the Undercity of Kurast grants a chance of obtaining Living Steel along with other Lair Boss Keys. This is the second most optimal way of farming Living Steel as its drop rate is quite high.

Living Steel can be obtained by killing Astaroth in Escalating Nightmares. Do note that although this rewards large quantities of Living Steel, it's drop rate is based on the randomized affix, making this the least efficient farming activity.
Astaroth Location and Unique Drops
In order to use your Living Steel, you first have to defeat Grigoire in the Hall of the Penitent. Doing so will spawn his hoard chest inside the boss area where you can use 12 Living Steel to open it.
Take note that Lair Bosses are now free to summon but their rewards now drop from their respective reward chests called hoards.
