Azur Lane Tempesta and the Corridor of Fog: Event Stages, PT and Dates

Azur Lane Tempesta and the Corridor of Fog is the October 2026 event with new pirate-themed ships, event stages and two ways to earn limited characters. It opened after maintenance on October 22, with combat stages available until 5 November 2026 at 06:59 GMT.

There is another deadline you shouldn’t miss. The PT shop and accumulated-point rewards remain claimable until 12 November at 06:59 GMT. You need to earn the points while the event maps are open, even if you intend to spend them later.

Azur Lane Tempesta and the Corridor of Fog dates

The seven-hour difference is correct after Britain’s October clock change. The later date is not an extension for playing event battles. Once the sorties are gone, any unfinished PT farming is over.

How to play and earn event points

Open Azur Lane Tempesta and the Corridor of Fog using the limited event banner, then choose the event’s combat stages. Clear sorties to earn event PT. Yostar’s Japanese publisher notice also identifies event daily missions as a source of points.

The Japanese Yostar notice calls the event currency フラスコ入り霧靄, literally mist in a flask. The English notice uses the term event PT. Both describe the points you earn in battles and use in the event’s reward panels.

Start with stages your fleet can clear reliably. Yostar’s Japanese event notice also describes a once-daily SP stage offering a large amount of event PT, plus an EX challenge for testing your fleet rather than farming materials. Check which stages are open on your server before planning your daily runs.

Járnbarðinn and Riyala Bey reward methods

Járnbarðinn is available in the PT exchange shop, where you spend collected points. She is also listed in the limited construction pool until November 5, but Yostar does not explicitly describe her as rate-up.

Riyala Bey comes from accumulated PT. Reach the required total during the event and claim the milestone reward; you don’t buy her from the shop. This means shop exchanges and your cumulative reward progress are separate decisions.

In Azur Lane Tempesta and the Corridor of Fog, check the PT shop and accumulated rewards separately. The English notice doesn’t specify Járnbarðinn’s exchange price or Riyala Bey’s milestone, so use the current event reward panels to see what you still need.

Story Mode and Corridor of Fog Medal

Yostar offers five Wisdom Cubes for reading the entire event Story Mode. The reward comes from completing the story rather than from rolling construction or buying something with event PT.

A Commemorative Album runs alongside the event. Finish its designated missions to collect stickers and exchange them for the Corridor of Fog Medal. The October English notice confirms the album and its reward without listing each sticker’s location or mission requirement, so check the live album rather than copying an old Tempesta checklist.

Azur Lane Tempesta and the Corridor of Fog also includes new augment modules, Meowfficers Alexander and Ólafur, costume rentals and the Marks of Treasure seven-day promotion. Their claim conditions are different from the main PT rewards.

What to finish in Azur Lane Tempesta and the Corridor of Fog

Prioritise the event battles you still need, collect earned daily rewards, finish Story Mode and check any unfinished album missions. Watch the event-specific construction deadline too: Merkuriy, Selimiye and Ormrinn Langi are marked rate-up there, while Járnbarðinn is merely listed as available.

Once you’ve collected all the points you can, there is time to claim Járnbarðinn from the exchange shop and Riyala Bey from the accumulated rewards panel. Don’t treat that later claim window as an opportunity to start new sorties.

If you’re arriving late to Azur Lane Tempesta and the Corridor of Fog, earn as much event PT as possible before the maps close, then use the later claim window to redeem what you’ve already collected. That’s the distinction that prevents missed rewards.
