Stronghold vs. Academy

As they say, "there's no defense against brute force." You need to level up the summoning silence skills (this magic is essential) and most likely Chaos magic. But honestly, I'm disappointed. Some of the spells are completely useless.

Imagine if he levels up a different class instead of a mage :O. Then all your silence spells become useless. You'll see what happens if the Academy mage becomes a warrior! And did you level up the silence spells? You'll be defeated by turn 3:15! So, if you don't know what to develop, turn him into a crazy fighter. And you'll crush him! + Goblins are there, and they will definitely help you.
