Bab 744: Gold Is Better Than White.

Only crown bearers and their lieutenants can fly in the arena. The rest are foot soldiers. Both sides have the same amount of crowns, but they have different amounts of lieutenants. Most of the crowns of the battle sage monkeys are emperor crowns with ten lieutenant spots, while most of the crowns of the Vipers have been demoted to the lowest commander crown with one lieutenant spot. So battle sage monkeys have a higher amount of airborne forces. 

Soverick is the one responsible for the changes to the crown. He created a massive advantage for the battle sage monkeys. Being airborne means they have a larger range of movement. They will also have a wider view of the overall situation, and they will be able to easily move to any location that needs assistance to support them.
