From the 19th challenge onwards and for every third challenge after that, you will receive pieces of the Archnemesis Totem Pole decoration to display in your hideout.

The challenge rewards are only obtainable in this league, and will be revealed in an upcoming news post. There are microtransaction rewards when you complete 12, 24, and 36 challenges. The new challenge league includes a set of 40 new challenges.You can create private league versions of these leagues, with mods that make the game harder. They have the same core mechanics and items. With 3.17.0, there are Standard, Hardcore and Solo Self-Found variations of the Archnemesis challenge league available.Archnemesis mods cannot be traded with other players.To prevent you having to backtrack, there are more than four possible locations where you may encounter petrified monsters in each area, but only the first four you encounter can be empowered and fought.These recipe mods yield substantially more dangerous encounters and have more valuable rewards. More than half of the available mods are created by combining other mods together on the same monster.By the time you have empowered and slain four petrified monsters in an area, you will have received the first reward four times. This results in a fight that has twice as many dangerous mods, and twice as many rewards. When you empower your second monster, it also has the mod you applied to the first monster. The mods you apply will accumulate as you play through the area.If you're able to successfully defeat the empowered monster, then you will receive the fixed reward that corresponds to that modifier. When you find such a monster, you can free it by empowering it with an Archnemesis mod. Over the course of each area you play, you'll encounter four monsters that are frozen in place, petrified and bound to the Archnemesis statue.You store these in a dedicated inventory panel so that they don't clutter your regular inventory. When you slay regular Rare and Magic monsters in the Archnemesis League, they sometimes drop an itemised version of a new Archnemesis monster modifier.As you play through the league, you'll discover more recipes and learn how to best utilise them to get the most valuable rewards. These mods can be combined in over 35 recipes to create new, more powerful and rewarding mods. It introduces around 60 new monster mods and allows you to customise your rare boss fights to control your level of risk and reward. Archnemesis is a challenge league that reinvigorates fights with rare monsters.All of your old characters and items are still present in the Standard and Hardcore leagues, but you're encouraged to join the new leagues, complete challenges and demonstrate your mastery of Path of Exile! Challenge leagues are a great opportunity for a fresh start in a new economy.
