The Basics
•Location: Stormbearer Point: This boss can be found in the Stormbearer Mountains, south of the Mondstadt city, which is fitting given its Electro theme and the stormy environment of the area.
•Appearance: The Thunder Manifestation appears as a large, floating orb with intricate patterns and an inner core that pulses with Electro energy. It's surrounded by smaller, orbiting orbs that contribute to its defenses and attacks.
Combat Mechanics
•Phases: The battle with the Thunder Manifestation involves several phases:
•Initial Barrier: It starts with a protective barrier that must be broken by dealing sufficient damage.
•Orbital Orbs: After the barrier is broken, it deploys smaller orbs that orbit it, which can be destroyed for additional damage or used in elemental reactions.
•Elemental Shifts: Throughout the fight, it might change its behavior or summon additional Electro-based attacks or minions.
Attacks:
•Electro Blasts: Fires rapid Electro projectiles that can track or spread across the battlefield.
•Lightning Strike: Summons lightning from above to strike specific areas on the ground.
•Electro Rings: Creates rings of Electro energy that orbit it, occasionally sending out waves of damage.
•Thunder Storm: Generates a localized storm that can summon Electro-based enemies.
Strategy 
•Elemental Weakness: The Thunder Manifestation is weak to Pyro and Geo. Using characters like Klee, Diluc, or Ningguang can be effective.
Avoiding Damage
•Use characters with high mobility or crowd control abilities like Venti or Jean to avoid the spread of Electro blasts or lightning strikes.
•Characters with invincibility frames during their abilities can safely dodge through some of its area-of-effect attacks.
DPS Focus
•When its barrier is down, prioritize the main body for damage. Characters with high burst damage like Xiao or Hu Tao can be very efficient.
Elemental Reactions
•Triggering Overload (Pyro + Electro) can help in damaging both the boss and its orbs. Overload can also disrupt its attack patterns momentarily.
•Healing and Shielding: Given its Electro damage output, having a healer like Bennett or a shield like Zhongli can mitigate damage significantly.
Team Composition
•DPS: Characters like Razor or Keqing, who can exploit Electro reactions, or Pyro characters like Xiangling.
•Supports: Characters like Fischl for consistent Electro application or Xingqiu for Hydro reactions.
•Healer: Characters like Diona for healing and Cryo resonance, which can increase attack speed with Pyro.
•Utility: Zhongli for his shield or Sucrose for Elemental Mastery boost and crowd control.
Rewards
•Defeating the Thunder Manifestation provides:
•Primogems
•Hero's Wit
•Mystic Enhancement Ore
•Talent materials like "Teachings of Prosperity" or higher tiers for character ascensions.
Tips: 
•Orb Prioritization: Start by breaking the orbs to expose the core, but be mindful of when to switch targets back to the main body.
•Elemental Mastery: Characters with high Elemental Mastery can benefit from the frequent reactions, especially Overload.
•Timing and Positioning: Learn to predict the timing of its Electro attacks to minimize damage taken. The battlefield can become electrified, so staying on the move is key.
•Practice: Understanding the boss's patterns and knowing when to switch between offense and defense can significantly improve your performance.
The Thunder Manifestation combines the challenge of elemental reaction management with the strategic need to handle its multiple threats, making it a memorable encounter in Genshin Impact for both casual and dedicated players.
