Genshin Impact includes a series of boss battles, which can be very challenging if you are not ready for them. Some new content has been added in Update 2.0, and the battle with Baal is one of them.
It is important to note that this boss battle cannot be truly won. However, the problem is that you have to really fight Barr until a scene takes over when she loses a quarter of her health. If you die too early, the fight will repeat. Make sure you have a capable healer like Bennett, Qiqi, or Jean, because just like the Raiden Shogun, Baal uses a lot of electrical moves to make a heavy blow.
Long-range characters like Ganyu, Klee, and Ningguang are best suited for this battle. You should avoid using the Electro character, because Baal is immune to all attacks from this element.
If you are using one of Genshin Impact’s short-range characters, try to hit Baal and then retreat regularly. Don’t stay by Baal’s side for too long, or you will regret it. Diluc, Hu Tao, Ayaka, Eula, Kazuha, and Noelle are all good choices, if you have one.
Baal will first rampage on the battlefield at lightning speed, while using electric slashes, if you do so, it will hit you. Do keep a safe distance, and create shield. Baal also summons lightning from the sky to strike the area around him.
When Baal activates her Vision Seeking Decree, you will know that the battle is about to end, which will prevent all your characters from using thier elemental moves. At this point, avoid as many attacks as possible until the battle ends in a cutscene.
