Future king.

The Dark Elf is indeed invincible; lightning dealing 690 damage and excellent defense cannot be broken. I built 40 Druids, 140 Archers, and 20 Unicorns to counter spells. As a result, Furies destroy Dryads and Swordsmen, Unicorns don't reflect any spells, Archers fall after two lightning strikes, and Druids are taken down by Dragons and Minotaurs. It would all be fine, but in addition to all this, the city needs to be captured within 2 months.
In general, he needs to either completely remove the defense or completely remove the Chaos.
