Genshin Impact:
Key strategies:
Don't use Ganyu's burst, it wastes time
Make sure you're properly aligned with the Thunderhelm Lawachurl. Sometimes he will attempt to strafe around you so adjust accordingly. The goal is for him to charge straight into the wall behind you. If he has an angle, he will end up in a corner. You then want to shoot at him and kill a slime with AoE.
Once one Electro Slime dies, the Abyss Mage will spawn. The Lawachurl's shield should now be out or low so you want to shoot directly at the Abyss Mage's shield which most of the times will break alongside Xiangling's Pyronado. Wait for the Pyronado to hit the mage and shoot at the ground to have the bloom deal maximum damage.
