This is Path of Exile at its most fun von smrtsmiths Blog

This is Path of Exile at its most fun: the screen jammed with skeletons, a necromancer at their back raising the fallen ones pretty much as fast while you can kill them. Fortunately, finding friends is straightforward, which makes trading simple, offering much more opportunities to get new gear.
The developers have chosen to POE Chaos Orb forgo in-game currency, encouraging players to barter, while vendors just offer further customisation tools as rewards. Try to trade something in and you will be shown identify scrolls or fragments towards an orb which will modify something you already own. Players are trading the many time along with the only problem you may have with it can be keeping up while using chat log.
Path of Exile costs nothing-to-play. I haven't mentioned this yet since it keeps slipping my thoughts, something I take to be a very good sign. As usual, there's money to become spent for the cosmetic aspects, buying a pet which will follow you about, modifying the look of one's character or treating yourself to a different character animation. Players will pay to contribute custom content towards the game and POE Exalted Orb you will also find your wallet grants you the chance to increase your personal stash and character limit. The game doesn't press you on any one of these, nor would it be interested in asking someone to pay to create your character more efficient or to consider shortcuts.
