In Diablo II Resurrected, Corpsemourn is part of the Ornate Armor 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 55 to carry this item. This Ornate Armor has a Strength Requirement of 170 before it can be used.
The Ornate Armor is the exceptional version of this Armor. It can be upgraded to the elite version by putting it into the Horadric Cube. After hitting the transmute button it will be called Sacred Armor. The most basic (normal) version is called Ancient 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.
