In Diablo II Resurrected, Steel Carapace is part of the Shadow Plate category and one of many unique Armors in D2R. It is a relatively big item, taking 6 Blocks of space if you want to store it in the inventory or stash. Your character needs to reach at least the Required Level of 66 to carry this item. This Shadow Plate has a Strength Requirement of 230 before it can be used.
This is already the elite version of this Armor, so it cannot be upgraded any further. The normal version is called Full Plate Mail, while the exceptional version is Chaos Armor.
Note: If this item can have sockets, you might be able to get some runes and get one of the runewords as a result - if you place them in the correct order. Have a look at our builds to find out which items make the most sense for the character you're currently playing.
