In Path of Exile 2, currency refers to a variety of in-game items that players use primarily for crafting, trading, and upgrading gear. Unlike traditional games where currency is represented by gold or coins, Path of Exile relies on various orbs and scrolls as its economic system. Each type of currency ( https://www.ssegold.com/poe2-currency ) has a specific function in modifying or enhancing equipment, as well as being used for trade in the game’s player-driven economy.

Some key types of PoE 2 currency include:

1. Chaos Orbs: These are one of the most commonly used currencies in trades and are used to re-roll modifiers on rare items.

2. Exalted Orbs: Extremely valuable, these are used to add a new random modifier to a rare item, making them essential for high-tier crafting.

3. Divine Orbs: Allow players to re-roll the values of modifiers on items, which is essential for perfecting gear for end-game content.

4. Chromatic Orbs: Reforges the color of sockets on gear, helping players fine-tune their items to match their builds.

5. Orb of Regret: This currency refunds a passive skill point, allowing players to adjust their builds by respecing points spent in the skill tree.

These orbs and other items, like Jeweller's Orbs and Orbs of Fusing, are used to enhance and perfect character builds and trade with other players. Path of Exile's deep crafting and trading system revolves around these valuable items.
