Path of Exile 2 Forbidden Rites is a brand new Event League introduced in Patch 0.5.5. You'll need to create a new character and progress from Campaign all the way to Endgame.
The most unique aspect of this Event League is its duration. Forbidden Rites will continue until Path of Exile 2 1.0 Full Release, meaning you'll have ample time to experience the new content.

PoE 2 has answered many player questions. Below, EZG has compiled these questions and, combined with currently available information, analyzed 8 Forbidden Rites Challenges that are not yet fully confirmed.
Launch Time
Forbidden Rites will officially launch on September 4th at 1 PM PDT. Before the event begins, PoE 2 servers will be shut down for Patch 0.5.5 deployment. The official team will announce separately the specific maintenance time.
Once the servers reopen, you can create new event characters by selecting Standard, SSF, or Forbidden Rites in the character creation interface. Joining is largely the same as with the previous leagues. With Forbidden Rites open, Runes of Aldur will not close; the two leagues will run in parallel until Path of Exile 2 1.0 full release.
Therefore, players still playing in Runes of Aldur can continue completing existing challenges without worrying about their progress being immediately wiped. However, both leagues have completely independent economies; characters cannot interact across leagues or trade.
Fresh Economy
For many veteran PoE2 players, the appeal of the new Event League lies in the process of starting from scratch. One of the biggest features of Forbidden Rites is its fresh economy.
Since all players will start from zero, old characters, gear, and economy cannot be transferred to the new league. New gear and Path of Exile 2 currency will re-enter the market. You will need to level up your character, accumulate gear, and determine which items are worth keeping and trading.
As players progress to endgame, market prices and demand will constantly change. The earlier you discover high-value base items or gear, the easier it will be to gain an advantage during the early stages of the game.
The official announcement also confirms that new Item Filter information will be released before Forbidden Rites launch. Players planning to rush to Endgame at launch can adjust their filters in advance to reduce interference from useless drops and find worthwhile gear and PoE2 currency more quickly.
Trial of Chaos
The content brought by Forbidden Rites needs to be distinguished from the changes in Patch 0.5.5 itself. PoE 2 official team has confirmed that the changes and other improvements in Trial of Chaos are not limited to Forbidden Rites but will apply to the entire Path of Exile 2.
Therefore, even if you continue using existing characters from Runes of Aldur or Standard, you will still be able to experience Trial of Chaos adjustments. Additionally, Runes of Aldur will be integrated into Core Game after Patch 0.5.5, and related content will later be accessible in Standard.
Private League
Forbidden Rites also supports Private League, which is convenient for fixed teams or players who prefer unique rules and gameplay. However, POE 2 Private League content is not available in advance. You can create a private league now, but you still need to wait until the event starts on September 4th to join.
Challenges
Forbidden Rites introduces new Challenges, which reward exclusive Cosmetic Rewards upon completion. Currently, the official POE2 rewards include Locust Footprints Effect, Locust Swarm Finisher Effect, Wildwood Guardian Pet, Wildwood Affliction Level-up Effect, and Hideout Statue.
These rewards are related to the progress of Forbidden Rites challenges. Currently, it's confirmed that the officially mentioned challenge directions for the eight challenges include completing Campaign Ritual, defeating specific Rare Monsters, and reaching Level 90.
While the exact names and completion conditions haven't been fully confirmed by the official POE 2 team, we can speculate based on currently available preview information and community materials.

The Riteseeker
The Riteseeker may require completing 11 Rituals within a Campaign. During Forbidden Rites event, Rituals will appear in PoE 2 Campaign area. The easiest way to complete them is to complete them whenever you see a ritual while leveling up, rather than waiting until endgame to finish them all.
The Hunter
The Hunter will probably require you to kill specific Campaign Bosses in Path of Exile 2. These may include The Crowbell, Constrictor Queen Kabala, Blackjaw the Remnant, The Great White One, Akthi the Final Sting and Anundr the Sandworm.
Not all of these are mandatory bosses in PoE2 main storyline. Don't skip optional bosses during progression to speed up the main quest; otherwise, you'll need to rerun Campaign map after Endgame.
The Ascendant
The goal of The Ascendant is to obtain all 8 Ascendancy Points, requiring completion of the character's corresponding Ascendancy Trial. This challenge does not require a specific Path of Exile 2 class or Ascendancy; simply unlocking all of your character's Ascendancy progress is sufficient.
The Master
The goal of The Master is to reach Level 90 for your character, and this may be the most time-consuming part of the challenge. After completing Campaign, leveling up is primarily done through Atlas maps. When entering higher-level PoE2 maps, be extra careful not to die to avoid significant experience loss. It's best to choose relatively easy maps that you can reliably complete.
The Reliquarian
The Reliquarian may require identifying 50 unique items. This is calculated based on the number of identified items. Unique items are continuously gained during Campaign and Endgame, so normal gameplay should be sufficient to complete it.
The Nameless
The Nameless refers to a mysterious entity related to Ritual within Forbidden Rites and is a key element of this Event League content. As you progress through Ritual content, you'll gradually encounter events and endgame content related to The Nameless.
Currently leaked information suggests that The Nameless requires completing 18 related objectives. Specific requirements will be available on the in-game Challenge panel after the official release of Path of Exile 2 Forbidden Rites.
The Cartographer
The Cartographer requires fully allocating the main Atlas Passive Tree. After entering POE2 Endgame, you need to continuously advance Atlas, unlocking more maps and Atlas Passive Points, and then allocate all the points you acquire.
You need to continuously explore new map areas and advance Atlas, earning Atlas Passive Points, and finally fully allocate the main Atlas Passive Tree to complete the challenge.
The Vanquisher
The Vanquisher is the final challenge, requiring you to defeat a specific Path of Exile 2 Endgame Pinnacle Boss, which may include the fully-powered Vessel of Kulemak, The Bodach, and Tangmazu.
These three bosses demand higher levels of gear, damage output, and survivability from your character. Therefore, it's best to wait until you've completed Atlas progression and leveled your characters significantly before focusing on this challenge.
Path of Exile 2 Forbidden Rites has confirmed the new league's launch date and answered our questions. Regarding the eight Challenges, some names and specific requirements still need to be confirmed upon official release, but based on current information, most objectives can be achieved gradually as you progress through the game.
