All twenty empowered scarlet fiends. I did all twenty. It took so much farming for my team to become strong enough to beat them. Even then, about 5 or 6 of those fights still came down to pure dumb luck. Never again 🤣
As far as I know this only plays for the second forms of some Brutal difficulty fights (Like the ones that drop Infernal Quintstones). Also I like how it uses that guitar riff at 0:12 like in a couple of Minstrel Song themes.
