The Master Builder can be unlocked once the Home Base reaches Town Hall Level 4. To do so, you can use the boat located just outside the village and travel to the Builder Base.

Gear Up in Clash of Clans
Once Builder Hall Level 4 is reached, the Master Builder in Clash of Clans can enter the Home Village to Gear Up three defensive buildings:
- Cannon: A Level 7 Cannon in Clash of Clans can be Geared Up if the Double Cannon is Level 4 at the Builder Base. This upgrade costs 1,500,000 Gold and allows the building to burst fire with a salvo of four cannonballs. It also reduces range.
- Archer Tower: A Level 10 Archer Tower in Home Base can be Geared Up if at least one such tower is at Level 6 on the Builder Base. This upgrade costs 4,000,000 Gold and adds a Fast Attack mode. The new mode makes the tower attack faster but reduces the range.
- Mortar: A Level 8 Mortar in Home Village can be Geared Up if the Multi-Mortar in Builder Base is Level 8 or more. The gearing up costs 8,000,000 Gold and allows the building to fire in bursts of three shells.
Notably, Master Builder in Clash of Clans is only available for Gear Up if he is free in the Builder Base, and only one building of each type can be Geared Up at once. Additionally, the process of Gearing Up can always be reversed.
