Lost Ark’s The Bitter Cold Update Adds a New Extreme Kazeros Raid on August 12

Lost Ark’s August update, The Bitter Cold, arrives on August 12 with a fairly narrow focus: a new Extreme version of Kazeros Raid: Act 2. The raid event runs for four weeks, from August 12 through September 16, while Amazon Games and Smilegate RPG prepare for server merges later in the month.

The new 8-player raid is available in Normal, Hard, and Nightmare difficulties. Normal and Hard allow individual resurrection, but only once per run. Nightmare removes that safety net entirely, so clears there will be a much stricter test.

Players who beat Brelshaza in Nightmare can earn 45,000 gold and 200 Coin of Fire and Ice tokens. Normal and Hard also reward gold and tokens, though at lower amounts. There are also once-per-roster first clear rewards, plus the “Lord of the Bitter Cold” title for clearing Nightmare.

Outside the raid, the update is mostly cosmetic. According to the official release page, the 2025 Summer Swimsuit skins are returning, with a new option for the Guardianknight. There’s also a Panda World avatar set, a panda pet, and a Panda Ride mount that’s basically a bamboo rickshaw pulled by a panda.

Don’t expect the usual spread of progression events this time. With server merges scheduled to begin August 26, the team isn’t adding new attendance events or progression updates until sometime in September.
