In Path of Exile, players have to forget the modern concept of capitalist economy, because there is only a barter system in this game. All things sold by NPC merchants in the game require POE Currency, which is the game’s artificial currency, and they appear in many forms and become increasingly rare.
Unlike gold or other coins, POE Exalted Orb has no other purpose other than currency value. Each POE Currency has a function to modify items, which means they can also be used as crafting materials.
Path of Exile is a ruthless game, the trading system can be arbitrary. At the same time, this is a loot-based game, but Path of Exile's items are far more than just the eye. Their item descriptions have their own dictionary, where the difference between more and addition may be the life and death of the player character. Therefore, do not treat product descriptions at face value.
Path of Exile provides a hardcore mode in which the character's death is permanent. This may sound like an attractive way to play. But if the player is new to Path of Exile, please avoid it like the plague. And, in addition to getting POE Currency in the game, players can also try to buy POE Currency online.
