The Hexagonal Kill Formation required six casters and was laid out according to Heaven, Earth, Yin, Yang, and the five elements. Each position must be occupied by one person while the primary caster took charge in the center of the formation. Everyone else was to provide backup.
This formation was able to combine all six casters' powers into one. No matter which direction Cahya walked into, the caster situated in that direction would have the united power of all six of them.
Cahya was the strongest in all of China. She couldn't be defeated simply by increasing numbers against her. However, the Hexagonal Kill Formation could concentrate the powers of the six casters into one, making it the perfect weapon to deal with Cahya.
