Matchup & timing
Use the hero to reveal the map, defeat manageable Treasure guardians and claim nearby Treasures; avoid trading the hero’s health for a reward guarded by a force it cannot beat. Use its training ability when Hussars are needed; keep the hero safe while units are being produced. Withdraw between fights when damaged so regeneration can restore health instead of risking the hero for marginal damage. If it collapses, keep a friendly unit or building nearby and protect the recovery period until it reaches 100 hit points.
Use the campaign hero to support cavalry
Cooper has 900 hit points and 5.0 speed, with attacks of 14 hand, 20 ranged, and 14 siege damage. He claims Treasures, trains Hussars, and regenerates. If he collapses, leave a friendly unit or building nearby until he reaches 100 hit points and can be revived. Keep him near the cavalry he supports.
Keep cavalry and hero abilities working together
Cooper’s 20 ranged damage and Hussar training ability let him support a mounted force while claiming Treasures. At 900 hit points, he should not be left alone in a major fight. If he collapses, maintain a friendly presence through his recovery to 100 hit points and revival.
Protect the Hussar trainer between objectives
When Cooper is not producing Hussars or claiming Treasures, keep him near allied units rather than leaving him in the open. His ranged and siege attacks add utility, but 900 hit points are limited for a campaign hero. A nearby friendly unit or building is needed if he collapses before regenerating 100 hit points.
