you must be in the same tier of the one you want to upgrade your merc, then, you have to go to an healer of the same tier of yours and click on the button upgrade.... Merc.reply, as it changed now? I click on my merc an it goes to my hero's upgrade screen. So I'm I missing something here? I just started to play at lvl 12 now,my merc at lvl 11 an its the first one you get.
