The 404 Chick is already one of the stronger chickens available in Grow a Chicken Fighter, but its default ability does not always make the most of its potential. One way to improve the chicken is to transfer the Cycle of Ash skill from the Radiant Fenghuang through the fusion system.
This combination creates the 404 x Ash fusion, a powerful build that can perform well in the current meta. The difficult part is obtaining both chickens, especially because the 404 Chick has an extremely low hatch chance. This guide explains the full farming route and how to fuse the two chickens correctly.
What Do You Need for the 404 x Ash Fusion?
You need two specific chickens before you can create the build: the 404 Chick and Radiant Fenghuang. Both can be obtained through different egg types, meaning you will need to work through separate farming paths before you can complete the fusion. Here are the main requirements:
404 Chick
- Obtained from: Cursed Eggs
- Hatch chance: Less than 1%
- Rarity: Secret
Radiant Fenghuang
- Obtained from: Royal Eggs
- Hatch chance: 1%
There is also another option if you are having trouble obtaining either chicken. Both the 404 Chick and Radiant Fenghuang can hatch from the Blazing Egg during the Hot Event. If the event is active, farming Blazing Eggs gives you another opportunity to find the chickens you need.
How to Get the 404 Chick
The first major goal is obtaining the 404 Chick. Since it comes from Cursed Eggs, you need to build a farming chain that eventually allows you to produce those eggs consistently. You can begin with the Classic Rooster, which can generate Nest Eggs. From there, your progression should look like this:
- Start with Classic Rooster and use it to generate Nest Eggs.
- Hatch Nest Eggs until you obtain Cosmo Brat.
- Use Cosmo Brat to farm Scratch Eggs.
- Continue hatching Scratch Eggs until you obtain NPC Chick.
- Use NPC Chick to start farming Cursed Eggs.
- Hatch Cursed Eggs until you obtain Stone Face Chicken.
- Use Stone Face Chicken to produce Cursed Eggs more efficiently.
- Continue hatching Cursed Eggs until the 404 Chick appears.
Cosmo Brat is especially useful early in this process because it has a 100% chance to produce Scratch Eggs. This makes it one of the better chickens for moving through the early part of the farming chain.
How to Get NPC Chick
After obtaining Cosmo Brat, use it to generate Scratch Eggs. Your next target is the NPC Chick, which has approximately a 12% chance of hatching from Scratch Eggs.
Once you get NPC Chick, switch your focus toward Cursed Eggs. NPC Chick has an 80% chance to produce a Cursed Egg every two minutes, making it a useful stepping stone toward the more efficient Stone Face Chicken.
You do not need to stop at NPC Chick, however. The goal is to use it to produce enough Cursed Eggs to eventually obtain Stone Face Chicken, which significantly improves your farming speed.
How to Get Stone Face Chicken
Stone Face Chicken is an important part of the 404 Chick farming route because it can produce Cursed Eggs with a 100% drop rate. It has around a 19% hatch chance from Cursed Eggs, making it considerably easier to obtain than the 404 Chick.
Once you get Stone Face Chicken, use it as your primary Cursed Egg producer. Its guaranteed egg production makes the process much more consistent.
At higher levels, its production timer can also improve to approximately one Cursed Egg per minute. This is a major upgrade compared with NPC Chick’s two-minute production cycle, allowing you to generate and hatch Cursed Eggs much faster.
After setting up Stone Face Chicken, the remaining part of the process is mostly luck. Keep hatching Cursed Eggs until you finally obtain the Secret-rarity 404 Chick.
How Rare Is the 404 Chick?
The 404 Chick is one of the hardest parts of the entire fusion to obtain. Its hatch chance from Cursed Eggs is below 1%, so you should expect to hatch a large number of eggs before seeing it.
Because of this, the best approach is to focus on improving your Cursed Egg production rather than trying to rush the process. A Stone Face Chicken with a faster production timer can save a considerable amount of time over the course of a long farming session.
Keep producing and hatching Cursed Eggs until the 404 Chick finally appears. Once you have it, you can move on to the second half of the fusion.
How to Get the Radiant Fenghuang
The second required chicken is the Radiant Fenghuang, which comes from Royal Eggs with a 1% hatch chance. Although this is still rare, the Royal Egg farming route can be made much more efficient with the right chickens. Your progression should look like this:
- Obtain Cosmo Brat.
- Use Cosmo Brat to farm Scratch Eggs.
- Hatch Scratch Eggs until you obtain Crest Rooster.
- Use Crest Rooster to generate Royal Eggs.
- Hatch Royal Eggs until you obtain Rooster of Fortune.
- Use Rooster of Fortune to produce Royal Eggs consistently.
- Fuse Rooster of Fortune to improve its egg production speed.
- Continue hatching Royal Eggs until you obtain Radiant Fenghuang.
The key chicken in this route is Crest Rooster, which has a 60% chance to produce Royal Eggs. This allows you to move from Scratch Eggs into Royal Egg farming without relying entirely on random egg sources.
How to Get Rooster of Fortune
After obtaining Crest Rooster, use it to build up your Royal Egg supply. Continue hatching Royal Eggs until you get Rooster of Fortune.
Rooster of Fortune is particularly valuable because it has a 100% Royal Egg drop rate. Once you have it, you can rely on it as your main Royal Egg producer instead of depending on the lower production chance from Crest Rooster.
You can also fuse Rooster of Fortune to improve its egg-laying speed. A faster production cycle means more Royal Eggs over time, which ultimately gives you more chances to hatch the Radiant Fenghuang.
How to Get Radiant Fenghuang
With a reliable Royal Egg producer ready, simply continue hatching Royal Eggs until you obtain Radiant Fenghuang. Its hatch chance is approximately 1%, so this stage can still require a significant amount of farming.
The good news is that once Rooster of Fortune is producing Royal Eggs at a faster rate, you can generate attempts much more quickly. Keep your Royal Egg production running while you work toward the Radiant Fenghuang.
You only need one Radiant Fenghuang for the fusion, but make sure it has the Cycle of Ash ability that you want to transfer to the 404 Chick.
How to Fuse 404 Chick With Cycle of Ash
Once you have both the 404 Chick and Radiant Fenghuang, you are ready to create the final build. The fusion itself is straightforward, but there is one important step you should not skip.
Follow these steps:
- Open the Fusion menu.
- Select your 404 Chick.
- Select the Radiant Fenghuang.
- Check the abilities displayed in the fusion menu.
- Find the Cycle of Ash skill on the Radiant Fenghuang.
- Lock Cycle of Ash before confirming the fusion.
- Double-check that the correct ability is locked.
- Confirm the fusion.
Locking the skill is the most important part of the process. The fusion system can otherwise select a different ability, potentially leaving you with a result that does not have the skill you were trying to transfer.
Once the fusion is complete, the result should be the 404 x Ash build, combining the 404 Chick with the Cycle of Ash ability.
Is the 404 x Ash Fusion Worth Getting?
The 404 x Ash fusion is worth pursuing if you are looking for a stronger endgame chicken build. The 404 Chick already has strong potential, and adding Cycle of Ash gives it a more useful ability combination than simply relying on its default skill.
The main downside is the amount of time required to obtain the ingredients. You need to farm through both the Cursed Egg and Royal Egg progression routes, and both final chickens have low hatch chances.
The 404 Chick is particularly difficult because its chance is below 1%. However, once you have the right egg-producing chickens, the process becomes much more manageable. The Radiant Fenghuang is also rare at 1%, but its farming route benefits from the guaranteed Royal Egg production of Rooster of Fortune.
The 404 x Ash fusion is one of the more powerful builds you can work toward in Grow a Chicken Fighter. Getting it requires two rare chickens, with the 404 Chick coming from Cursed Eggs and Radiant Fenghuang coming from Royal Eggs.
For the 404 Chick route, work toward Cosmo Brat, NPC Chick, and Stone Face Chicken to improve your Cursed Egg production. For Radiant Fenghuang, use Cosmo Brat, Crest Rooster, and Rooster of Fortune to build a reliable Royal Egg farm.
Once you finally have both chickens, the fusion is simple. Select the 404 Chick and Radiant Fenghuang, then make sure to lock Cycle of Ash before confirming. That final step is what allows you to create the 404 x Ash build you were farming for.
