Tips and Tricks for Stage 7

Use Cryo Characters

List of Characters
Eula	Rosaria	Ayaka
Layla	Mika	Diona
Shenhe	Ganyu	Qiqi
Chongyun	Kaeya

For defeating the Abyss Herald and the Abyss Lector in their second phase, we recommend using a Cryo character to destroy their shields. Using Cryo characters can also freeze the Abyss Herald during its second phase.

Summon Electrograna Quickly

As much as possible, summon the Electrograna whenever you get the chance, as when summoned, gives your characters increased Normal and Charged Attack DMG while also triggering Elemental Blasts.

Attack the Abyss Lector in Okuden

In the Okuden stage, you will fight both the Abyss Lector and Abyss Herald at the same time. Prioritize on attacking the Abyss Lector first, as the Abyss Herald will approach you making it easier to hit both of them in one spot.
