Hey guys! I'm new here and looked through other posts and just couldnt find my answer. I recently discovered the ability to call reinforcements (allies and comrades). Until now, I have never been able to defeat a level 300 archwitch...that is, until now. However, I have noticed that even when I call in reinforcements and defeat the archwitch through a comrade, my heart levels have dropped. So was it a fluke that I had a full heart, because I haven't changed anything at all? What am I doing wrong?
