In Diablo II Resurrected, Rattlecage is part of the Gothic 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 29 to carry this item. This Gothic Plate has a Strength Requirement of 70 before it can be used.
This is the normal version of this Armor. It can be upgraded to the exceptional version by putting it into the Horadric Cube. After hitting the transmute button it will be called Embossed Plate. After that, it can be upgraded even further by repeating the steps and you will receive the Elite Version (Lacquered Plate).
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.
