Builder Hall 10 is the final Builder Hall level in Clash of Clans. Reaching BH10 serves as the dream achievement for all Builder Base fans.
Unlocking BH10 introduces two exciting new additions: the X-Bow and the Electrofire Wizard. These new additions greatly amplify the thrill and excitement of Builder Base attacks.
In order to maximize your base’s potential, it is important to follow a proper upgrade order guide specifically designed for Builder Hall 10.
By strategically prioritizing the right upgrades, you’ll gain the upper hand when confronting other BH10 bases, ensuring a smoother and more successful gameplay experience.
Start by Getting the New Buildings
One of the advantages of upgrading to Builder Hall 10 is the limited number of new buildings you need to construct. Only two new structures, namely the X-Bow and Mine, are introduced at this stage.
Once you have successfully upgraded to BH10, it is recommended to assign one of your Builders to immediately start the construction of the X-Bow.
Simultaneously, utilize the other builder to quickly set up the Mine. The construction of the X-Bow needs 4,400,000 Builder Gold and takes 7 days to complete.
On the other hand, the Mine can be instantly built, allowing you to work on the upgrade of Star Laboratory.
It is recommended to keep X-Bow at level one for now. We will work on it later.
Star Laboratory
Now that you have reached Builder Hall 10, you will encounter considerably stronger bases. In order to successfully tackle these powerful opponents, it is necessary to upgrade your troops.
To accomplish this, prioritize upgrading your Star Laboratory. By upgrading your Star Laboratory, you gain access to higher-level troops that can significantly improve your attack strategies.
Therefore, allocating resources and time towards upgrading your Star Laboratory should be considered a top priority to increase your chances of victory.

Builder Barracks
Having successfully upgraded our Star Laboratory, it is now time to unlock the powerful Electrofire Wizard. This extraordinary troop has the ability to switch between two distinct modes, each with its own unique set of abilities.
In his fire mode, the Electrofire Wizard inflicts increasing damage over time, similar to the destructive power of an Inferno Tower.
On the other hand, in his Electro Mode, this mighty warrior can unleash chain attacks, reminiscent of the devastating capabilities of an Electro Dragon.
Given his remarkable usefulness and firepower, unlocking the Electrofire Wizard should be among your top priorities at Builder Hall 10.

Hence, it becomes necessary to ensure both hero machines are thoroughly upgraded to achieve optimal results in your BH10 attacks.
By prioritizing the upgrades of both hero machines, you can effectively maximize their potential and significantly improve the outcomes of your attacks.
| Level | Upgrade Cost (Builder Elixirs) | Upgrade Time |
| 31 | 4,100,000 | 7 days |
