As the battle goes on, take note of your Monolith or Stone Towers and replace any as needed, and place Verge Officers or Soldiers to help destroy the Cannon Trains. Then watch the enemy Stronghold and kill the Boommeister as soon as he appears in the same way as the first time. Four or five Bolt Towers should be enough.
After this, place Bolt Towers (with Monolith or Stone Towers for protection) next to your Stronghold to defend it from the Hawkmen, Lion Riders, and Cannon Trains. The Boommeister must be killed as soon as possible after starting the stage, preferably with a Deadly Shot and by placing a Verge Officer like Aegis right next to him. Tips: One of the most difficult Vergeway stages.
