Orbs of Chance are primarily applied to particular base item types in the hopes of obtaining a particular unique item, a process referred to as chancing. However, the resulting item is most commonly a magic item, and uncommonly a rare item. Because of this, players should carefully weigh the cost of using up Orbs of Chance to obtain a specific unique against the cost of simply trading for that unique. The chance of creating a unique item is different for every unique and depends on the rarity of that specific unique. The base item’s item level doesn’t limit the type of unique items that can be obtained, so it is possible to obtain what are otherwise map-only unique items.
These unique items have high values and are worth to try: "Headhunter, Leather Belt", "Zerphi’s Heart, Paua Amulet", "The Pandemonius, Jade Amulet", "Atziri’s Reflection, Golden Buckler", "Farrul’s Fur, Triumphant Lamellar", "The Eternity Shroud, Blood Raiment", "Kaom’s Heart, Glorious Plate", "The Perandus Manor, Chateau Map", "Unnatural Instinct, Viridian Jewel", "The Green Nightmare, Viridian Jewel", "The Green Dream, Viridian Jewel", "Emperor’s Wit, Cobalt Jewel", "Inspired Learning, Crimson Jewel", "Soul Ripper, Quartz Flask", "Bottled Faith, Sulphur Flask", etc.

An item filter can highlight base items as they drop for use with an Orb of Chance.
Care should be taken to use an item with high enough item level to get a desired number of sockets or other effects based on item level such as a Vaal Orb corruption.
Notably, unique items specific to past temporary leagues, such as Headhunter or Voll’s Devotion, can be obtained with an Orb of Chance only while standing in a map to which the appropriate league’s mod has been added with the Map Device. Depending on the item, this can be one of the most profitable ways to use Orbs of Chance since they can be used to obtain items that are nearly unobtainable otherwise.
In races or at low levels, players may also find using Orbs of Chance on good base item types useful for quickly crafting a potentially usable magic or rare item.
