How to Beat Immernachtreich Keep

Get All Nachtraben's Regards

Nachtraben's Regards will randomly appear as a solo buff or in groups around the challenge area. To get the buffs, you only need to step on it's spotlight, and it will follow you, no need to stay in a single area!

Use AoE Anemo Skills

Sucrose or Kazuha's skills are perfect for gathering enemies in a single area, which will further spread the Electro-Charged Elemental Reaction! Their skills can also absorb an Element and since the majority of enemies are all using Pyro, you can also inflict Overloaded.

Break Abyss Mage Shields Fast

Three Abyss Mages will appear as soon as you beat the Pyro Slimes, break their shield with either Hydro or Electro to quickly defeat them.
