In Diablo II Resurrected, The Oculus is part of the Swirling Crystal category and one of many unique Orbs in D2R. It is a relatively small item, taking 3 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 42 to carry this item.
This Weapon is One-Handed, so your character can use an additional weapon or shield on the other arm.
The Swirling Crystal is the exceptional version of this Orb. It can be upgraded to the elite version by putting it into the Horadric Cube. After hitting the transmute button it will be called Dimensional Shard. The most basic (normal) version is called Jared's Stone.
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.
