How to Get Master Builder in Clash of Clans

The Master Builder is the dedicated builder for the Builder Base, a separate progression system in Clash of Clans with its own buildings, troops, and mechanics. He works similarly to the regular builders in your Home Village but operates exclusively on the Builder Base side of the game.
Beyond that, he has a unique ability that regular builders don't have. Once you reach the right progression milestones, he can travel to your Home Village and perform Gear Up upgrades on select defenses, enhancing them with an alternate fire mode.
He's also a required part of unlocking B.O.B, the sixth builder in the game. In this article, we'll explore how to get the Master Builder in Clash of Clans, what he can do, and how to use him in both villages.

Article Summary

The Master Builder is the dedicated builder for the Builder Base, unlocked by reaching Town Hall 4 and sailing to the Builder Base via the boat on your shore
Once at the Builder Base, he handles all construction and upgrades there automatically
He can also travel to your Home Village to perform Gear Up upgrades on three defenses: Cannon, Archer Tower, and Mortar
Gear Up requires Builder Hall 4, specific building levels in both villages, and the Master Builder to be free in the Builder Base
Gearing up the Cannon costs 1,000,000 Gold and gives it a burst mode; the Archer Tower costs 3,000,000 Gold and adds a fast attack mode; the Mortar costs 6,000,000 Gold and allows it to fire in bursts
B.O.B is the sixth builder, unlocked by reaching Builder Hall 9, building the B.O.B Control, and completing four tasks: gear up all three defenses, upgrade a troop to level 18, upgrade a defense to level 9, and reach a combined hero level of 45
Once B.O.B's Hut is placed in your Home Village, B.O.B becomes a permanent sixth builder there, and the Master Builder no longer needs to travel between villages
How to Get the Master Builder

The Master Builder becomes available once your Home Village reaches Town Hall level 4. At that point, a boat appears on the shore of your village. Tap it to sail over to the Builder Base, where the Master Builder will walk you through the new area. From there, he handles all construction and upgrades in the Builder Base automatically. Arriving at the Builder Base is all it takes to get him working.
How to Use Gear Up
To use Gear Up, you need to upgrade your Builder Hall to level 4 and meet specific building level requirements. The Master Builder can Gear Up three defenses in your Home Village, each with its own requirements and cost.
Defense | Home Village Level | Builder Base Requirement | Cost | Effect |
|---|---|---|---|---|
Cannon | Level 7 | Double Cannon Level 4 | 1,000,000 Gold | Burst mode |
Archer Tower | Level 10 | Archer Tower Level 6 | 3,000,000 Gold | Fast attack mode |
Mortar | Level 8 | Multi-Mortar Level 8 | 6,000,000 Gold | Burst fire mode |
Once you meet the requirements for a defense, tap it in your Home Village and select the Gear Up option. The Master Builder will then travel over and begin the upgrade. Keep in mind that he must be free in the Builder Base to take on a Gear Up task, and only one building of each type can be Geared Up at a time. The process can always be reversed.

How to Unlock B.O.B

B.O.B is the sixth builder in Clash of Clans, created by the Master Builder. To unlock him, you need to reach Builder Hall level 9 and build the B.O.B Control. From there, you upgrade the B.O.B Control to level 5 by completing four tasks:
Gear Up all three defenses in your Home Village (Cannon, Archer Tower, and Mortar)
Upgrade one Builder Base troop to level 18
Upgrade one Builder Base defense to level 9
Reach a combined hero level of 45 across your Builder Base heroes
Once the B.O.B Control reaches level 5, the B.O.B's Hut becomes available to place in your Home Village. After placing it, B.O.B takes over as a permanent sixth builder there, freeing the Master Builder to stay in the Builder Base full-time.

Final Words
The Master Builder is a straightforward unlock that opens up a useful set of tools for your Home Village. The Gear Up upgrades are worth doing early, and working toward B.O.B is one of the better long-term goals in the Builder Base since the sixth builder has a noticeable impact on your Home Village progression.
