Ok so sadly i cant seem to conquer the colossus... Regardless of that i have to agree with everyone if there is to be such a huge amount of experience gained during your conquest you should be able to spend it on better up grades. You get to a point where basically all your using is epic creatures, yet they are finished after a few trifles with the "Iron Fortress" Honestly i love these games and its great but i feel there should be afew more skills to obtain, such as more health or even on the epic units where they lack you could make them become strong in. I do have to add all time favorite game series seriously keep it up.
 "Epic War 5"){kind=icon}
