Thread: [Event 28] Crucible of Combat vs The Demon Envy (Union Event)

There's a bug with Yukimura - on auto-skill, whenever she tries to use her second skill, it instead moves on to auto-attacks.

So auto-skill with Yukimura is 1-2 Skills from Yukimura -> auto-mode. As a work-around, you'll need to use her first skill manually, then her second skill, then go to auto-skill.
EDIT: Oh, you can't use the second skill on party members unless they have over 10 Burst, I guess? Yeah, have fun doing debuffs manually.
