In Path of Exile, Orbs have a high value and can be used for a variety of purposes. Some Orbs are incredibly expensive, others are useful only for high-level players. Some are also very valuable for trading with other players. One such Orb is the Chaos Orb, considered the silver standard in the player-driven economy.

Orb of Alteration

Orb of Alteration rerolls the modifiers on a magic item, and is generally used for magic gear early-game. It can also be consumed on a Map to change the affixes on it, which is useful for the late-game Atlas progression.

Orbs of Alteration are a vital currency for crafting a variety of items, particularly in the early and mid-game when more powerful crafting methods like Exalted or Chaos Orbs may be too expensive. Orbs of Alteration are also the base price for obtaining many vendor recipes.

Alternatively, players can acquire orbs of Alteration through player trading, either on the marketplace or in in-game trade chat. This method is usually more effective than attempting to farm them through NPC vendors.

Orb of Regrets

This item allows a player to respec their character's passive skill tree. It can be purchased from Yeena in Forest Encampment for two Orbs of Scouring. It can also be found in various chests and containers throughout Wraeclast and in divination cards.

It can be used to reroll the modifiers on a unique item, and it can also be combined with Orbs of Regret to create the Book of Reform. It can also be resold to vendors for a small profit. It is recommended to use this item on low tier maps to fill your Delirium rewards faster.

Orb of Vaal Implicits

The Orb of Vaal Implicits is a currency item that corrupts an item, modifying it unpredictably and making it unable to be modified again (including restoring imprints). It can also corrupt Strongboxes, resulting in a random set of ilvl 1 implicit mods.

The results of this corruption can be very powerful and valuable, but it's also possible for the item to become "bricked" with a bad modification, such as changing the item's socket colors or removing a socket, links, or affix.

This system adheres to the risk vs reward philosophy that is central to path of exile currency guide looting systems, and it can be a very lucrative way to improve an item.

Orb of Reforging

This is probably the most useless currency in the game. It has a chance to upgrade a normal item to a rare one with up to four linked sockets, but this is often wasted on 5 or 6-link items which are already quite good.

It also has a small chance to improve the Quality of an item up to 20%. This is useful for Armour and Weapons, but not for Spell-casters as the quality increases base damage.

It drops from monsters and can be exchanged for other currencies at Yeena in The Forest Encampment. It is also possible to buy them from other players for a considerable amount of Chaos Orbs.

Orb of Chaos

One of the most important currency items in Path of Exile, the Chaos Orb offers a large variety of benefits and implications. Players can acquire them by completing various league mechanics and events, selling rare items to vendors, or using it in meta-crafting to guarantee one Veiled modifier.

It can also be used to corrupt a Rare item, although this is not an efficient use of it early in the game. However, it can be useful later on to reroll properties of uncorrupted Rare items such as Jewelry or Rings, or even Amulets with good Affixes that cannot be Bench-Crafted.

Orb of Exalted

The Orb of Exalted is an important currency in Path of Exile, allowing players to reroll rare item mods. This is a useful tool for high-level players who want to craft powerful rare items, but cannot afford to buy them in the marketplace.

It is dropped by Al-Hezmin, the Hunter, and can also be obtained from other players in game. It can also be found in monsters and chests of maps under his influence.

However, it is not recommended to spam these orbs. Since already influenced influences override normal Exalted mods, it is more efficient to use them only for rerolling critical mods or affixes that increase damage/ HP/ resistances.

Orb of Mirror of Kalandra

A Mirror of Kalandra is the rarest and most valuable currency item in Path of Exile. It can be dropped by monsters, chests and destructible containers (including Arcanist's Strongboxes). It is over a thousand times rarer than an Exalted Orb and is only found by a very small percentage of players.

It can be used to duplicate an existing item, which is a great way to get a copy of a high-end rare item. It can also be used to duplicate a custom-crafted item, which can give players a significant upgrade in stats over an unupgraded version of the same item.
