Heroes of the Academy - Academy

Level 23 – and completely without magic. And if you encounter an enemy BEFORE getting the super ability, the mage will face a quick and painless death.

Heroes are exactly what you need against an enemy, and that's what I'm mentoring you on. The tactic consists of building a level 5 guild of mages. There is a high probability that either Armageddon or Summon Phoenix will be available there. Consequently, we either develop Expert Chaos or Expert Summoning, and definitely, Expert Enchantment for the second hero, give him 7 new golems, and fight to the last, inflicting huge damage on the enemy army. The opponent will definitely be surprised when 3-4 such heroes attack him in one turn. They cause damage to the army, but gain no experience. Moreover, by that time, the main hero will have a counterspell, and a battle of warriors is predicted. I'll reveal a secret: I will have mini-artifacts, so after the destruction of my unit stack, they will be resurrected.
This tactic has been tested on Hero difficulty, and it can be confidently said that after level 23, the game can be stopped.
