Vortex Gaming

Esther tactics areInitially 3~4bars filled, use Wei (up to 2 hits if possible),

Use Wei when the 117-line shield appears (up to 2 hits), and continue using it while countering. (up to 2 hits here as well)

Use Bastian when destroying the giant's arm at 60 lines.

Use Lahart during the 30-line stagger. (If the DPS is fast, Lahart might not be ready, but you can just use a DPS Esther after the stagger.)

There may be incorrect parts as I'm making this while trying on the first day.

Please let me know in the comments and I will correct it immediately.

The explanation seems a bit messy, so I will make a simple cheat sheet and upload it soon.
