Heroes Ascension

I created a detailed description of the pagoda. I hope I did a good job representing the defenders. Will it be overpowered with the Ki monks? Here's a scheme for any castle under Ascension: 7 levels with a triple upgrade + 3 levels selectively, which can replace some of the seven, + 1 level after building the Grail. Two buildings that increase growth. Should peasants be the weakest units, even in Ascension? If not, which neutral units should be used as a "benchmark" with all stats at 1?
