Imps in battle... they get killed, we resurrect them and send them to the Demons, it's not bad to have another hero with Imps as well... in total, 15 Demons per battle, 20 battles, 300 Demons... on large maps, with a long game and the right strategy, you can really accumulate a lot... building a Castle for other creatures doesn't make much sense compared to defense, because compared to a hundred Demons, 10 Ifrits look weak... plus, don't forget about the Demon increase.
