New units. Their discussion and selection of upgrades.

3) I always thought the same, but when I played the last time, it turned out that forest archers can deal more damage even with a bow. I was surprised. It seems that when enemies have high defense, it makes sense to take alternate archers even with a unicorn bow.

You just need to use "Master Archers" selectively - in general, it looks like this: against creatures of levels 1-4, "Master Archers" deal more damage; against creatures of levels 5-7, forest archers deal more damage (thanks to the 50% defense penetration; the higher the creature's defense parameter, the greater the bonus for forest archers). The presence of the "Unicorn Bow" does not affect the bonuses of forest archers.
