I'm just anxious why you not summon the 3 Crypt Brothers and blesses every unit giving them unique skills from melee units to warlocks and all. Also, why not capture dismantled horses thus saves time for Healers to have horses ridden. 😅
According to wiki: Peasants (except for Wolf Peasants, as they don't have ability to pack horses) with pack horses gather 60 units of rice and water instead of 15. The horse itself gathers 45 units of rice and water.
if you look at 7:04 there is a button that you have to click. but the townsquare upgrade was added in the WotW dlc, so you cant in the very base game. but it is included in the zen edition
