To gain a strong advantage in the mission, prioritize obtaining the first two chests. Implement the following strategy:

Start by deploying an unbound unit on the right side while sending fliers along with a melee unit on the left to engage and defeat the Prowlers.

Once the Prowlers are defeated, maintain the push and eliminate the Footmen, allowing you to seize control of the tower. If possible, proceed to capture the right tower without compromising the security of the left one.

While focusing on the towers, remain vigilant about the chests to ensure they are not overlooked. These chests offer valuable resources and should not be missed.

After successfully capturing both towers, initiate a dual-sided push with melee troops. Keep Maiev occupied to divert her attention from your forces, allowing the Pyromancers to deal damage from a safe distance.

Coordinate your units effectively, ensuring the melee troops engage in close combat while the Pyromancers provide ranged support. This combined effort will maximize your offensive capabilities and increase your chances of success.

By following this strategy and effectively managing your resources and unit positioning, you can maintain control of the towers, neutralize Maiev, and utilize the Pyromancers to deal significant damage to the enemy forces.
