Genshin Impact’s Version 4.2 introduces five new Local Legends that players can challenge in the new locations of Fontaine. These formidable foes, scattered across the enchanting landscapes of the Fontaine and Morte regions, bring unique abilities and battles to test even the most seasoned Travelers. In this comprehensive guide, we'll delve into the locations, strategies, and achievements associated with each of the new Local Legends.
New Local Legends in Fontaine and Erinnyes Forest
The Fontaine region and Erinnyes Forest are now home to five Local Legends: Mageblade Corrouge, Rocky Avildsen, Liam, Chassanion, and Deianeira of Snezhevna.
Mageblade Corrouge: The Enigmatic Jellyfish
Location: Southwest underwater waypoint near the Weeping Willow (accessible after completing "The Wild Fairy of Erinnyes" world quest).
Mageblade Corrouge, the first Local Legend, floats in the center of a water-filled chamber. To defeat this jellyfish, utilize the Xenochromatic Octopus powers. Repel the projectiles by redirecting them toward the jellyfish, dealing substantial damage. This counter is simple yet potent, making Mageblade Corrouge the easiest of the Local Legends.
Achievement: Mageblade Corrouge Achievement.

Rocky Avildsen, a robust opponent, poses a considerable challenge. His powerful punches and AoE attacks can be deadly, so consider bringing a shielder for survivability. Master the art of dodging to prevail in this intense battle.
Achievement: Rocky Avildsen Achievement.

Liam: Elemental Havoc in the Pond
Location: Northeast of the Weeping Willow, near a contaminated pond (requires completion of "The Wild Fairy of Erinnyes" quest).
Liam, a Local Legend with devastating AoE Elemental attacks, demands caution. His Pyro-infused assaults can be fatal, and a single hit might prove lethal. Bring a healer or shielder to enhance survivability, ensuring victory and unlocking the Liam Achievement.

Chassanion: Depths of the Morte Region
Location: Varies based on whether the Sealed Ruined Tower is unsealed.
For players yet to unseal the tower, teleport to the underwater waypoint south of Fort Charybdis Ruins. If the tower is unsealed, enter its platform and swim downward. Defeating Chassanion involves redirecting bubbles using the Xenochromatic Octopus's abilities.
Achievement: Chassanion Achievement.

Rewards and Achievements
Defeating these Local Legends not only grants players various achievements but also rewards them with Primogems, treasure chests, and, in some cases, unique items like the Mysterious Xenochromatic Crystal.
