like upgrading is possible only in the town but it effects your base attack, bonus attack and turn time aswell which are all war related. Its not supposed to be a clicker so it doesnt get faste, but you get more power over time. You may got one shot because you had low power. As I said in the description Power is used both as currency and as tower defense, so you shouldnt go to war while low on power. Ah thanks about the dialogue
