Content Update 3.18.0 -- Path of Exile: Sentinel

The Sentinel Challenge League

• Challenge leagues are a great opportunity for a fresh start in a new economy. 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!
• In the Sentinel Challenge League, ancient constructs have been unearthed across Wraeclast. You will harness the power of these Sentinels to control your level of risk and reward on the battlefield. When deployed, they follow you for a short time and empower your enemies, greatly increasing both their difficulty and reward.
• There are three classes of Sentinels. Stalker Sentinels empower a moderate number of enemies in sequence as you encounter them. Pandemonium Sentinels empower a wide swath of monsters at once in a quick burst. Apex Sentinels only empower rare or unique enemies but have a very strong effect.
• The Sentinel Controller can be used to customise the behaviour of your Sentinels. Filaments may be arranged on the controller to channel power to its nodes, each of which affect your Sentinels in different ways. These filaments may be moved around as often as you like in order to experiment with your ultimate Sentinel playstyle.
• When your Sentinels run out of charge, they can be combined together with a Power Core to assemble a new, fully-charged Sentinel that inherits properties from both of the husks you disassembled. This hybrid Sentinel may also gain special properties such as an exclusive variant base type or modifiers that can only come from the assembly process.
• You may uncover or assemble Unique Sentinels which behave in very specialised and powerful ways.
• Recombinators are a rare form of currency that allow you to apply the Sentinel Assembly process to your actual items. Take any two pieces of equipment from the same item class and combine them together. The results are unpredictable but can merge the best elements of each item to create something of unprecedented power.
• With 3.18.0, there are Standard, Hardcore and Solo Self-Found variations of the Sentinel challenge league available. They have the same core mechanics and items. You can create private league versions of these leagues, with mods that make the game harder.
• The new challenge league includes a set of 40 new challenges. These are much harder than normal, so we have significantly increased the rewards. Pieces of the Ophidian Armour Set are received when you complete 6, 12, 16 and 20 challenges. Upon completing 24 challenges you will receive the Ophidian Wings. Pieces of the Ophidian Lord Armour Set are received as microtransaction rewards when you complete 28, 31, 34 and 36 challenges, and completing 38 challenges will award you with the Ophidian Lord Wings. These challenge rewards are only obtainable in this league.
• From the 19th challenge onwards and for every third challenge after that, you will receive pieces of the Sentinel Totem Pole decoration to display in your hideout. The Totem Pole permanently showcases how many of the Sentinel challenges you completed during the league.
