Continually summoning ‘friends’ to use as a barrier while each one also heals her? While being impervious to red attacks?
How in the hell has anyone managed to defeat her? I was playing with 4* heroes including Kasreck and was going continuously for 10 minutes, never once managing to knock her health down more than 10% before she managed to build it back up to max. I was about to quit when she eventually sarted killing off my heroes one by one. Sometimes the abilities of the bosses just astound me in this game.
