Several people seem to be struggling on this stage, so I decided to release a video showing me passing it.
On the first section, if you don't stun the Shade at the start, leave, and re-start the stage. If you simply do "Retry", the outcome will be the exact same. On the up side, when you get into a loop where he does get stunned, he will be stunned on every retry.
Section 1: Ignore the Shade till there are only the Shade and 2 enemy's left - Your priority is to stun-lock Shade for as long as you can - Rose Knights shield can stun him a lot if there is another enemy around as it will bounce to him multiple times.
Section 2: Focus the left section. Your Prima Donna is highly vulnerable here and you need to keep her safe.
Section 3: Very similar to section 2. If you're using paid hero's, placing Big Guy behind Tracker is an easy way to pass this stage, but being F2P you don't have the option, so you need to out-last Tracker and focus her down last. Just send the occasional stun her way.
This took me around 30 attempts total, and is quite heavily luck based.
Good luck :)
Sorry about the volume - Recording software recorded it a bit low...
