Well, I wanted to be the first to tell you about this, but the message somehow went to the wrong place :'(
You're not entirely right about the cavalry: yes, the riders themselves are indeed "too proud," they won't even scratch themselves, but their horses start to snort and shake their manes like ordinary horses. ))
I also encountered obstacles; in my case, they were just ordinary iron sticks lying on the ground.
And one more thing: doesn't the cyclops' "invulnerability" ability remind you of the saying "it's like talking to a brick wall"? :)
