Lost Ark has added "Kazeros Raid Act 3 & Finale Extreme" through its regular update on September 23.
Extreme is limited-time content that adjusts combat patterns and difficulty based on the final gates of the existing Kazeros Raid Act 3 and Finale. First, Act 3 Extreme will run until October 21, followed by Finale Extreme from October 21 to November 18.
In addition, a matchmaking mode for the Shadow Raid "Belgardin, the Arbiter of Death" has been added, and the "Soft Bean Cake Harvest" event utilizing Chaos Rifts and the Kurzan Front lines has begun.

UPDATE 01
Act 3 Extreme, which reorganizes the final gate of Kazeros Raid "Act 3: Pitch-Black, Night of the Storm," has been added. The event runs for a total of four weeks, from September 23 until before maintenance on October 21. Afterwards, Finale Extreme will run from October 21 to November 18.
Act 3 Extreme is 8-player content consisting of three difficulty levels: Normal, Hard, and Nightmare. The required item levels for entry are 1,730 for Normal, 1,770 for Hard, and 1,780 for Nightmare, and players must complete the main quest "Continuing Mission." Entry attempts are provided once per week per Roster, shared across all three difficulties. In Normal and Hard, players can revive without limit upon death, but revivals are impossible in Nightmare.
The rewards are also substantial. Defeating Mordum grants 20,000 Gold and 150 Lightning Coins in Normal, and 50,000 Gold and 200 Lightning Coins in Hard and Nightmare. Unlike standard raids, players can receive gold rewards regardless of whether the character is designated for gold earning. Regardless of difficulty, first-time kills additionally award a Legendary Card Select Pack, Hero Gem Select Chest, Gem Recrafting Reset Ticket, 100 Lightning Coins, and 1 Chaos Coin.
In particular, first-clear rewards for Nightmare include the Legendary Title "Lord of Thunder," an exclusive emote pack, and 200,000 Gold Bullion. Clearing up through Finale Extreme Nightmare in the future will reward a Relic-grade Title as an achievement reward. Lightning Coins obtained from clears can be exchanged for various items at a dedicated crafting NPC. However, Ancient Core Select Chests can only be crafted after clearing both Act 3 and Finale Extreme.


UPDATE 02
Matchmaking mode has been added to the Shadow Raid "Belgardin, the Arbiter of Death". The required entry item level is 1,750, the same as the existing Normal difficulty, and players must complete the main quest "After the Echo Clears." Entering solo or forming a party/raid of 2–7 players and matching for remaining spots is supported. Entering after forming a premade party through Party Finder is also possible.
In matchmaking mode, combat balance is adjusted according to the number of participants. Unlike the existing raid, which strictly required gathering 8 players, adventurers can now challenge Belgardin more casually with any party size they prefer.
The types and quantities of clear rewards are identical to Normal difficulty. However, gold is granted as 50% regular Gold and 50% Bound Gold. Bonus rewards per gate are available, but loot auctions will not take place, and Sidereal Energy will not appear.

UPDATE 03
The autumn event "Soft Bean Cake Harvest" has also begun. The event runs from September 23 until before maintenance on October 21.
During the event period, Soft Bean Cake Legion monsters will appear in Chaos Rifts and Kurzan Front lines. Defeating them gives a chance to spawn a "Songpyeon Ember," which yields one of several rewards upon interaction. Consuming Rest Bonus increases the spawn rate of Songpyeon Embers. Standard Fate's Embers will continue to appear as usual.
A stamp book event in the form of login rewards is also active. Players receive 1 Songpyeon Stamp on weekdays and 2 on weekends, with tiered rewards granted based on the total accumulated count.
Rewards include a Leap Legendary Card Pack III for 5 stamps, a 2026 Chuseok Head Skin Chest for 10 stamps, a Lion Dance Mount Select Chest for 15 stamps, and a Chuseok Mokoko Pet Select Chest for 20 stamps. Any stamp book rewards not claimed within the period will be delivered to Universal Storage after the event ends.
