Diablo 4 has recently launched a collaboration event with Fanta, giving players a chance to claim a brand-new portal cosmetic for free through the event page — the Citron Whirl Portal. Although the reward itself is free, the redemption process is a bit complicated, especially since the event page is mainly designed for mobile devices. Still, if you follow the steps correctly, PC players can also complete the redemption without much trouble.
This crossover event is part of the promotion for the upcoming new Diablo 4 expansion, and Fanta has also introduced a new flavor called Crimson Cherry. The event is tied to a QR code printed on Fanta cans. After scanning it, players can enter the event page, play a mini-game, and unlock the reward.
Citron Whirl Portal - the Event Reward
The main reward for this event is the Citron Whirl Portal, a portal appearance reward introduced through the Diablo IV x Fanta / Coca-Cola collaboration. In essence, it is an in-game Portal Cosmetic used to change the visual appearance of your portal. It does not provide any stat bonuses or gameplay advantages. According to Coca-Cola’s official event page, this cosmetic features a bright orange swirling design and is one of the limited-time digital rewards in the collaboration. After completing the event and successfully linking a Battle.net account, players will receive the reward in their account inventory when Diablo IV: Lord of Hatred launches on April 28, 2026.
How to Obtain the Citron Whirl Portal
Although the portal is free, players still need to meet one requirement first: they must register for and sign in to a Coca-Cola account, then complete a mini-game on the event page to unlock the free Citron Whirl Portal.
In addition, it is important to understand the redemption rules in advance. According to the official FAQ, players can claim up to 5 rewards during the entire event period, with a limit of 1 reward per week. Each specific reward can only be redeemed once per account. The FAQ also mentions that in the United States, players can participate without purchasing a Fanta product.
At the same time, players should pay close attention to the supported platforms. The official FAQ states that these rewards currently support Xbox, Battle.net, and Activision accounts, but do not support PlayStation, Nintendo Switch, Steam, or other platforms. If you are a Diablo IV player, the most important thing is to make sure that you link the correct Battle.net account; you may not be able to claim the reward successfully.
How to Join the Event on Mobile
Under normal circumstances, this event page is better suited for mobile devices. After logging in to the Coca-Cola event page, you need to find the Diablo 4 collaboration mini-game and complete its puzzle-combination challenge before you can redeem the reward.
How to Join the Event on PC
Although the page is intended mainly for mobile devices, the entire process can also be completed on a computer. The method is to use your browser’s developer tools to make the website think you are visiting from a mobile device.
Here are the steps:
1. Open Chrome or Brave.
2. Right-click on the page and select Inspect.
3. After opening the developer tools, click the device simulation icon at the top, which looks like a computer and phone.
4. In the Dimensions option, choose a mobile device model, such as iPhone 14 Pro Max.
5. Refresh the page.
6. The website will then think you are visiting from a mobile device, and the mini-game should display properly on your PC.
This method is especially convenient for players who prefer to complete the Battle.net account linking process directly on their computer.
How to Complete the Mini-Game
After entering the Diablo 4 event page, find “Shatter the Spell” and click Start to begin the mini-game.
The core gameplay of this mini-game is simple: you need to place the correct four items into the Horadric Cube and use Transmute to stop Mephisto’s eclipse.
The correct four ingredients are:
● A key
● An orange gem
● A lotus-like flower
● An orange elixir
Once all four items are placed into the Horadric Cube, click Transmute. The game will then play a short animation, showing that you have successfully completed the challenge.
How to Redeem the Citron Whirl Portal
Finishing the mini-game does not mean the reward will be delivered automatically. Since there may be multiple promotions on the event page, you need to scroll further down until you find the Diablo 4 reward section labeled “Citron Whirl” Portal.
After finding it, click Redeem Reward, and then follow the instructions to link your Battle.net account.
The account-linking process usually includes these steps:
1. Click the Battle.net button
2. Select your own Battle.net account
3. Check the authorization box
4. Click Allow
If everything goes smoothly, the page will confirm that your accounts have been successfully linked. At that point, the redemption process is complete, and all you need to do is wait for the reward to become available on April 28, 2026.
Conclusion
Overall, the reward from this Fanta x Diablo 4 collaboration is quite attractive, especially for players who enjoy collecting cosmetics. As a free reward, the Citron Whirl Portal is definitely worth trying to get. Although the process involves creating a Coca-Cola account, dealing with mobile-only page restrictions, and linking a Battle.net account, it is not too difficult once you know the right steps — especially if you use the PC method to simulate mobile access.
In addition, before participating, players should confirm both the redemption rules and the supported platforms. After all, the total number of rewards, the weekly redemption limit, and whether the correct account platform is linked will all directly affect whether you can successfully obtain this portal cosmetic.
For players getting ready for the upcoming expansion, claiming the free Citron Whirl Portal is a nice bonus. And if you want to prepare your character more efficiently, you can also check out our Diablo 4 Gold or Diablo 4 Items.
