When using the infirmary our heroes don't regenerate health between waves, which is normal.



However Heroes (and possibly merchants?) you find in the floor won't heal either. Meaning they will die in a couple of waves before you can hire them. Since we have no way to heal them, and usually we don't have the dust to put towers with them, I suggest unhired heroes should be an exception to the healing rule.. they should regenerate between waves when using the infirmary.
