Gameplay tactics on the large map.

That's right, you can't really run away from vampires or blade dancers. And if you don't use Furies, you won't be able to break through, for example. So, they are expendable; it's more about strategy than tactics here. Either wait a week to gather Hydras and break through with minimal losses, or use Furies and pass through earlier.

There shouldn't be any problems with these either. Place the Furies in a corner, with Stalkers next to them, and a line of single Minotaurs or Stalkers in front, depending on the opponent's initiative. The hero will fire a couple of times, and the Furies and Stalkers will take down the approaching stacks. You can deal with the retaliation with those same single units.

Or, in a pinch, just put out Minotaurs. While the hero is shooting, they can withstand a few hits, and in the final stage, they are almost useless anyway.
