The Lord of Eroded Primal Fire is the ultimate boss challenge in the Natlan storyline of Genshin Impact. To progress effectively, players must confront this formidable opponent multiple times to gather essential materials for upgrading talents. Known for its complex attack patterns, defeating this boss requires careful preparation.
Fighting without Nightsoul characters makes this encounter significantly more difficult. Therefore, it’s advisable to assemble your strongest DPS characters from Natlan to improve your chances of survival. While the boss’s moves can be erratic, you can dodge or counter them effectively by closely observing its antics.
Locating the Lord of Eroded Primal Fire
To access this boss battle, you must first complete Act V of Chapter 5, "Incandescent Ode of Resurrection," in the Archon Quest. The initial encounter during this quest is automated but differs from the weekly boss fight style.
To defeat the boss in this Archon quest phase, focus on destroying the pillars created by Mavuika, followed by a powerful attack at the dragon’s shadow using the Traveler.
After finishing the quest, the trounce domain "Stone Stele Records" will be automatically unlocked west of the Stadium of the Sacred Flame. You can trigger the battle by interacting with the Natlan heroes’ monument.
Recommended Characters
Utilizing characters that deliver Nightsoul-aligned damage is key to overcoming this boss. Nightsoul characters can quickly deplete the boss’s shield and effectively dismantle any pillars that it summons.
Assembling a team exclusively from Natlan will be beneficial, thanks to their efficient use of the Nightsoul mechanics. Mavuika, Chasca, Mualani, or Kinich should serve as your main damage dealers, while Xilonen can help debuff enemies if your team relies on elemental damage.
If your roster lacks Nightsoul characters, rely on powerful DPS options such as Arlecchino, Xiao, or Navia to compensate.
Moreover, since the boss’s behavior can be complex, it is wise to bring a character capable of providing shields to your team. Citlali is an excellent choice, as she can also deal Nightsoul damage and complements elemental characters effectively.
If Citlali isn’t available, consider Zhongli or Noelle as alternative shielders. For long-range attacks, use characters like Ganyu, Neuvillete, or Yanfei. Including a healer, such as Sangonomiya Kokomi, Barbara, or Baizhu, will also be beneficial to sustain your team.
Understanding the Attack Patterns
The Lord of Eroded Primal Fire has a tricky attack pattern; it exhibits both short- and long-range strikes. Its agility means you need to respond quickly to avoid damage.
Also referred to as Gosoythoth in the game, here’s a breakdown of its attacks:
| Attack | Description | How To Avoid |
|---|---|---|
| Chasing Dark Orbs | Fires four orbs that track the character. | Dash sideways towards the boss to evade. |
| Dark Rain | Creates a rain of dark energy mixed with rocks. | Move to small gaps to minimize damage. |
| Ground Slice | Raises its sword to slice the ground, damaging those nearby. | Keep your distance to avoid damage. |
| Flame Sword Smash | Slams the sword into the ground, causing wide area burns. | Move away from the center to avoid being hit. |
| Forward Flame Sword Slice | Executes a forward slice with the flame sword. | Get closer to the boss or dash sideways to dodge. |
| Flame Waves | Inserts flame sword into the ground, releasing waves of fire. | Jump over the waves to evade when they approach. |
| Double Sword Smash + Laser | Simultaneously strikes the ground with both swords, followed by a laser attack. | Dodge to the edge of the field when you see the cross shape. |
| Forward Flame Slice + Dark Smash | Performs a series of attacks combining flame and dark sword moves. | Focus on dodging rather than approaching the boss. |
| Slash Flurry | Executes a combo of slashes with both swords. | Brace for the incoming flurry and dash in the opposite direction of the attack. |
| Ground Explosions | Causes random explosions from underground. | Run around to avoid and dodge when the boss reappears. |
| Flurry of Dark Energy | Shoots dark projectiles forward. | Run to the edge once you see the charge-up animation. |
Tips for Defeating the Lord of Eroded Primal Fire
This boss is one of the toughest opponents in Genshin Impact. Its attacks can deal severe damage, so caution is vital. Staying close can help you avoid many of its slashes and ranged attacks.
During the battle, it will summon three pillars, which you must destroy quickly using Nightsoul attacks. If not destroyed in time, the boss will unleash a massive dark ball attack, which is unavoidable and very damaging, even for those with shields.
Successfully eliminating the pillars will induce an exhausted state in the boss. Seize this opportunity to deal as much damage as you can.
As the fight progresses, the battlefield will shrink, complicating your ability to avoid attacks, so it’s best to defeat the boss as quickly as possible.
