Orb of Chance

An Orb of Chance is a currency item that can be used to upgrade a piece of normal equipment to a random rarity.

Vendor recipes
Orbs of Chance are common currency items that can be dropped by slain monsters, chests, and destructible containers. They also drop from Arcanist's Strongboxes.

An Orb of Chance can also be purchased from Clarissa (Act 3 and 8), Petarus and Vanja (Act 4 and 9) Lani (Act 5, 10 and Epilogue) and Yeena (Act 7) for an.

Spending
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 item and uncommonly a  item. and items modifiers can be removed  and so the chancing can continue with a single base 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 does not limit the type of unique items that can be obtained. But in the past it did.

An Orb of Chance cannot create:
 * Unique items that are only available through vendor recipes
 * Event prizes
 * Unique items that exclusively drop from certain bosses or in certain areas
 * Upgraded versions of items, like blessed items, fated items or items only available through corruption

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 corruption.

Notably, unique items specific to past temporary leagues, such as or, 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. However, GGG added some chancable league-specific item into core drop pool in version 3.14.0, thus the gaming community does not know the latest, official list of item that still requires Zana league mod to chance or drop.

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.

One can sell 4 Orbs of Chance to Yeena (Act 2 and 7), Clarissa (Act 3 and 8), Petarus and Vanja (Act 4 and 9), and Lani (Act 5, 10 and Epilogue) in exchange for an. Orbs of Chance can also be sold to vendors in exchange for magic amulets.
