Builder Hall 9 (BH9 max) in Clash of Clans is a crucial stage in the Builder Base journey, as it’s the level where players unlock the Battle Copter, a second hero machine that significantly enhances attack strategies.
With the “Builder Base 2.0” update, BH9 max operates on a two-stage attack system, making defensive layouts and troop compositions more complex and engaging.
Maxing out BH9 involves bringing all defenses, troops, and both hero machines to their highest possible levels for this Town Hall.
