Genshin Impact Peculiar Pinion: How to Get it, Thunder Manifestation Boss Guide

The Thunder Manifestation is a boss that arrived in Genshin Impact 2.1, but it's much more relevant now that Genshin Impact 2.2 has arrived.

Besides being a lot of fun, this new boss will drop ascension material necessary to level up Baal, Kujou Sara.

In addition, the Thunder Manifestation will drop the Peculiar Pinion, an item necessary to progress in Genshin Impact 2.2 Tsurumi Island.


The Thunder Manifestation is located on Seirai Island. To find this boss, players need to complete first:

Seirai Stormchasers quest

  • Head to Katheryne at the Adventurer's Guild in Inazuma City.
  • In Serai Island, players will meet two researchers that will take you to a Warding Stone.
  • Visit Neko, the talking cat in the shrine of Asase Island. He will teach you how to unlock the 4 Ward Stones
  • After deactivating the Wards, the Thunderstorm disappear.
  • The Thunderstorm Manifestation is right below the 4th ward stone.


  • If you do not find the charm hangars, look for Electrogranum (they are way high in the sky).
  • Unlock the two teleport waypoints first, so you can go back in case you miss a platform.

Thunder Manifestation Strategy

Thunder Manifestation attacks you directly instead of summoning minions, with an arsenal of Electro AoE abilities.


  • Watch out for the high burst damage of these boss abilities.
  • Keep control of your Stamina. Eating some food to reduce stamina consumption is helpful.
  • Your party should include ranged characters also characters that can break shields.
  • Prioritize Cryo and Pyro Elements.
  • When the lighting prism appears, just run. One wrong move and you are done.
  • The Thunder Manifestations attacks are predictable. Just make sure you do not run out of Stamina!
