The new annual expansion Siege of the Atlas has been out for almost a month. And many players have joined the new Archnemesis Challenge League. Each new league brings new balance patches, new trade economies, progress resets and various POE Archnemesis Currency.A lot of players will start over when a new league rolls out. I'm no exception, but I've learned that if I want to get better results in a new league, I need the best build first. But I should Buy POE Currency to power up my character.
