Secondary skills in Heroes 3.

1. Not everyone can always reach the archers in one turn.
2. I position the monsters before the battle (on the map), placing the slower ones near the archers...

This tactic is useful because, for example, even liches can be hidden behind skeletons in a battle against archangels.
1. Not always, but if there's a tactic, someone will definitely reach them, and the archers will be blocked.
2. You can position them closer to the archers, but the archers can still be attacked.
