With the launch of Path of Exile: Ascendancy, there is an upcoming league with it this March 4, 2016. It is the Perandus Challenge Leagues.
What is The Perandus Challenge League? Here are some brief background coming from the Path of Exile website:
Path of Exile Items: The Perandus Ascension
Before the Cataclysm, and before the Purity Rebellion, the Perandus family ruled over Sarn. Chitus Perandus was the first to navigate the Lord’s Labyrinth, the first to show that it could be beaten. He was aided immeasurably in this endeavour by his uncle, Cadiro Perandus.
Cadiro Perandus was a master of coin, the minister of finance in the kingdom both before and after his family’s ascension. His greed was legendary, for he was a devotee of Prospero, the ancient Azmerian god of the underworld, the earth, and all its boundless treasures.
Path of Exile Items: The Perandus Fall
The Perandus reign was brief, cut short by the Purity Rebellion and the death of Emperor Chitus. However, in the months before the revolt, a steady stream of unremarkable carts and wagons flowed from the capital, bearing a secret cargo to the far reaches of Wraeclast. By the time House Perandus fell, Cadiro had managed to steal the entirety of the kingdom’s treasury.
Players can go look for Lost Caches for fistfuls of glittering coins, which is the currency of the Eternal Empire. These can be exchange to Cadiro for a map to his family’s legacy, the Perandus Mansion. By completing all of 40 new challenges, players can get: Perandus Footprints Effect, Perandus Weapon Effect, and the Perandus Portal Effect. From the 19th challenge onwards and for every third challenge after that, players receive pieces of a Perandus Totem Pole decoration to display in their hideout. The Totem Pole permanently showcases how many of the Perandus challenges they completed during this league.
