This should showcase the level on mobile.
The level really can’t be beaten unless you go out of your way to kill the Blood Ogres or Gnolls before they are transformed into Blood Gnolls. That may be why you are seeing way more Blood Gnolls in your attempts at this stage than others’.
I must give this stage credit - as short as it is, the way it enables dps heroes or crowd control heroes to shine means either one could be brought in and come out successful.
