If they lose their mental control, they would instead suffer from the element-type beast’ recoil. This was equivalent to when strengthening-type beasts left its master’s body, or when a fighting beast-type beast abandoned a battle and run away. This was all caused by the master’s lost of control over their beasts… Furthermore, amongst all of recoils, the element-type recoil was the scariest one.
The element-type beasts possessed a destructive power. However, the moment it recoiled, the one destroyed would be its master.
