TIL that you can't replay completed exhibitions in this NeroFest. Cleared the first exhibition (the one with Herc) without recording it. I wish they didn't disappear after the first clear.
Don't have Nightingale for the buster set-up, so I decided to go budget (even the CEs used here can be obtained for free from previous events) with the buster support and see how much I can make a friend's Mordred rampage.
Music used:
Argent Coliseum - World of Warcraft Wrath of the Lich King
The Knight of Rebelion - Fate Apocrypha
