The currency system in Path of Exile revolves around a variety of different orbs and scrolls. Each currency item serves a specific function in the crafting and enhancement of a character’s equipment, or allowing restructuring of the character’s passive skill tree in the case of the Orb of Regret. Currency items are used to pay for items in player trading.
Currency items can be found as drops from monsters or chests, bought directly from different vendors in town, or received through the use of the vendor recipe system by trading specific configurations of items to any town vendor. Currency items play a large role in the player to player trading system, with rare orbs able to be traded for powerful equipment, or even other types of orbs that a player might need at the time for crafting.
