The Undead Tribe didn't feel too nervous... For them, it was just a somewhat tough battle, not even worth calling difficult.
No one fears death when fighting a Boss... getting disgusted to death is another matter entirely.
The claws of the Corpse Demon were indeed ferocious, but the protection built by the Defensive Knights wasn't so easily broken.
As for those Decaying Angels flying in mid-air, they were even easier to handle. 'Snow Cloud Peak' even temporarily handed over the command of the mages to 'Rain Falling on Mortal Dust', while he himself was holding a tablet and looking at something unknown.
'Rain Falling on Mortal Dust' was standing on top of a carriage, directing mages of various elements to attack in turns... not only did he have the Light Mages unleash a rain of light dots, but even the Space-Time Warlock's dragon was sent out once.
