Guardian Tales Raid - Winling/Scintilla/Toga/Vishuvac VS LvL 100 Erina

0:00 Run
1:13 Equipment
1:21 Engravings
1:31 Relics

Running into the corner at the start helps a bit with Erina's movement, but it's still very random, so you will have to adjust depending on it.

In general you want to pay attention to being close enough to your team when using Winling's extra skill. The duration is longer than the cooldown, so don't stress about always using it immediately, as in some cases Erina can cancel it if you do that.
Furthermore, make sure to be close enough to Vishu when she uses her extra skill. I'm aware that I didn't nail the chain timings here, but they do not have to be that precise. One thing to note though is that during 2nd chain you do not want to be much faster than this, as otherwise Erina will cancel the next Weapon Skill after the chain.

Chain Timings:
Winling 1.0
Vish 1.4
Toga 1.9 + Weapon Skill
Scintilla 1.1
