Builder Hall 10 is the final Builder Base level. Here are the best BH10 base layouts for defense, attack, and versus battles in 2026 with one-tap copy links.
Builder Hall 10 is the maximum Builder Base level in Clash of Clans. Reaching BH10 means you have access to the full suite of Builder Base defenses, including the powerful Mega Tesla and the O.T.T.O Hut that unlocks the Master Builder for your main village.
What Builder Hall 10 Unlocks
BH10 is a major milestone because it unlocks the O.T.T.O Hut — completing the O.T.T.O upgrade sequence sends the Master Builder to your Home Village permanently, where he acts as a 6th builder. This is one of the highest-value upgrades in the entire game.
New defenses at BH10:
- Mega Tesla — extremely high DPS single-target defense
- Roaster (upgraded) — air splash damage at maximum level
- Additional Cannon Car upgrade
- Guard Post at maximum level
BH10 Attack Meta 2026
The dominant attack strategies at BH10 in 2026:
Super P.E.K.K.A + Hog Rider: The classic BH10 combo — Super PEKKA tanks while Hog Riders deal damage and jump over walls. Very consistent for 2-star attacks.
Battle Machine + Mass Cannon Cart: The Battle Machine's Iron Fist ability combined with Cannon Carts creates a powerful ground push that can overwhelm bases lacking splash defense.
Night Witch + Minions: An air-heavy strategy that bypasses ground-based traps entirely. Effective against bases with weak Roaster coverage.
Best BH10 Defense Base Design
A strong BH10 defense base:
- Places the Builder Hall in the center, surrounded by Mega Tesla and Roaster coverage
- Uses the Mega Tesla to protect against Battle Machine approaches from any direction
- Positions Crushers along expected Cannon Cart pathing corridors
- Places Roasters where they cover the most airspace
- Uses the Guard Post centrally so reinforcement troops trigger mid-attack
How Versus Battles Work at BH10
In Versus Battles, both players attack each other's base within a time limit. The player with more stars wins — if tied, the higher destruction percentage wins. At BH10, most top-level players can reliably 2-star most bases. The difference between winning and losing often comes down to whether your base can hold the opponent to 1 star or force a lower destruction percentage.
Focus on bases that create tricky pathing for Battle Machines and deny easy access to the Builder Hall itself.
