Builder Hall 9 holds significant value for every Clash of Clans player as it provides the much-needed 6th builder for the Home Village. Unlocking this milestone becomes a priority for many.
To obtain the 6th Builder, players must build BOB Control at BH9, which presents them with specific tasks.
In addition to the advantage of an extra builder, Builder Hall 9 introduces two more notable features: an additional Reinforcement Camp and an exciting new defense known as the Lava Launcher.
To make the most of these new additions, it is important to follow the proper upgrade order when progressing through BH9.
By following this upgrade priority guide, you can efficiently advance towards the ultimate goal of reaching Builder Hall 10, the final level of the Builder Hall journey.
Get the new Buildings
To begin your Builder Hall 9 journey, it’s always recommended to prioritize getting the new buildings first. This step holds significance as the newly added buildings contribute significantly higher damage per second compared to the older ones.
Let’s take the Firecrackers as an example: by building new Firecrackers, you’ll gain an additional 55 damage per second for your base, whereas upgrading the older ones would only provide an increase of 12 damage per second.
Here is the list of new buildings that you receive at BH9:
- x1 Lava Launcher
- x1 B.O.B Control
- x20 Walls
- x1 Reinforcement Camp
- x1 Firecrackers
- x1 Spring Trap
- x1 Mega Mine
To kickstart the upgrade process, begin by constructing the BOB Control since it requires no build time. Next, focus on gettings the traps, followed by the construction of Firecrackers and walls.
Once those are in place, proceed to build the Reinforcement Camp. When the Reinforcement Camp is complete, it’s time to obtain the Lava Launcher.
Remember, it’s essential to avoid assigning more than one builder to these upgrades. Instead, use the second builder to work on the Star Laboratory upgrade mentioned in the next section.
Once all the new buildings are built, prioritize upgrading them to match the level of the older buildings.
Star Laboratory
It’s widely acknowledged that attacking BH9 bases can be quite challenging. To overcome this hurdle, focusing on troop upgrades becomes important. The Star Laboratory plays a major role in unlocking higher levels for various troops.
By prioritizing the upgrade of commonly used troops like Super PEKKA, Sneaky Archer, Boxer Giant, and Cannon Cart, you’ll significantly improve your attack strategies and become better equipped to tackle Builder Hall 9 bases.

Builder Barracks
Another important early upgrade to prioritize at Builder Hall 9 is the upgrade of the Builder Barracks.
This upgrade holds significance as it grants you access to the popular Hog Glider troop. Hog Gliders are exceptionally useful and widely favored among players at higher Builder Hall levels.

At Builder Hall 9, the Clock Tower undergoes an upgrade to level 9. This particular upgrade brings a significant benefit by increasing the boost duration from 28 to 30.
Having half an hour of accelerated speed for your upgrades and research is a massive advantage that should not be overlooked or neglected. So, prioritize the upgrade of Clock Tower as one of the early upgrades.

Elixir Storage
Upgrading the Elixir Storage at Builder Hall 9 holds great importance due to the substantial amount of Builder Elixir required for troop and hero machine upgrades.
Having a large storage capacity for Builder Elixir becomes highly beneficial, as it enables seamless upgrades for hero machines and troops.

Battle Machine
At Builder Hall 9, the Battle Machine undergoes a significant improvement with the addition of 5 new levels, elevating its level cap to 30.
These upgrades result in notable improvements to the Battle Machine’s hitpoints and damage per second. As a powerful hero machine, the Battle Machine plays a major role in determining the outcome of your attacks.
Therefore, prioritizing its upgrades is highly recommended to maximize its impact and effectiveness in battles.
| Level | Upgrade Cost (Builder Elixir) | Upgrade Time |
| 26 | 3,600,000 | 6 days |
| 27 | 3,700,000 | 6 days |
| 28 | 3,800,000 | 6 days |
| 29 | 3,900,000 | 6 days |
| 30 | 4,000,000 | 6 days |
Battle Copter
The Battle Copter is the second hero machine and its upgrades are equally important. To tackle powerful Builder Hall 9 bases effectively, it is important to have both the Battle Copter and Battle Machine well-upgraded.
Each machine plays a distinct role in different phases of an attack, making them equally important.
Both the Battle Copter and Battle Machine receive 5 new levels, with each level upgrade requiring 6 days to complete. This means that for the next 30 days, you will need to keep both of your builders occupied with upgrading these hero machines.
Meanwhile, it is essential to focus on farming Builder Elixirs for troop upgrades, as a lot of attacks will be needed to gather the necessary Builder Elixirs for all these upgrades.
If you consider yourself a casual player, you can try the alternate method of hero machine upgrades.
This method involves dedicating one builder to upgrade each hero machine, resulting in spending 30 days on upgrading the Battle Machine and another 30 days on upgrading the Battle Copter.
By doing so, the remaining free builder can be used to complete the upgrades mentioned in the next sections.
| Level | Upgrade Cost (Builder Elixir) | Upgrade Time |
| 26 | 3,600,000 | 6 days |

Gold Storage
For the upcoming upgrades, our focus will be on enhancing the Lava Launcher. Your current Gold Storage capacity won’t suffice for the final Lava Launcher upgrade.
Therefore, it is recommended to prioritize upgrading both of your Gold Storages to level 9 before proceeding with the Lava Launcher upgrade.

This combination of features makes the Lava Launcher an exceptionally high-priority defense building.

Given the strategic value of the Zappies and their potential impact on the result of an attack, upgrading OTTO’s Outpost should be considered a priority.
