In the ever-evolving world of Teyvat, the Obsidian Codex Artifact set has established itself as a cornerstone for Natlan character builds since its introduction in Version 5.0. Like a hidden gem waiting to be unearthed from the volcanic landscape of Natlan, these artifacts have become essential for players looking to maximize their Natlan DPS characters' potential. The set's unique synergy with Nightsoul's Blessing mechanics makes it as indispensable to Natlan characters as water is to desert travelers.

Where to Farm Obsidian Codex Artifacts

The coveted Obsidian Codex Artifacts can only be obtained from the Domain of Blessing: Sanctum of Rainbow Spirits, nestled in the Toyac Springs area of Natlan. This domain stands like a silent guardian at the entrance of a tunnel, just north of the People of the Springs tribe known for their therapeutic hot springs.

Unlike many domains in Teyvat that require solving intricate puzzles or completing challenging quests, accessing the Sanctum of Rainbow Spirits is refreshingly straightforward. Players simply need to approach the domain entrance and interact with it to begin farming. The domain alternates between dropping Obsidian Codex and Scroll of the Hero of Cinder City artifacts on different days, so timing your farming runs is crucial for efficiency.

Obsidian Codex Set Effects: A Game-Changer for Natlan DPS

The Obsidian Codex set has revolutionized build strategies for Natlan characters, functioning like a nuclear reactor that supercharges their combat capabilities when properly harnessed. The set bonuses are particularly powerful:

  • 2-Piece Bonus: When the character is under Nightsoul's Blessing state and on-field, all DMG dealt increases by 15%. This universal damage boost applies to every attack type, making it incredibly versatile.

  • 4-Piece Bonus: After consuming a Nightsoul point while on-field, CRIT Rate increases by an impressive 40% for 6 seconds. This effect can trigger once per second, essentially providing a constant CRIT Rate boost for characters who regularly consume Nightsoul points.

Best Characters for Obsidian Codex in 2025

As of early 2025, several characters benefit tremendously from the Obsidian Codex set:

  1. Mualani - The set was practically tailor-made for her. Her gameplay naturally involves consistent Nightsoul point consumption, allowing her to maintain nearly permanent uptime on the 40% CRIT Rate bonus. This enables players to focus artifact substats on CRIT DMG instead.

  2. Kinich - As one of Natlan's premier DPS units, Kinich's kit synergizes perfectly with the set's bonuses, turning him into a damage-dealing machine when properly built.

  3. Itzli - The newest Natlan character (released in January 2025) also benefits significantly from this set, with his unique playstyle that revolves around Nightsoul point manipulation.

  4. Upcoming Characters - With HoYoverse's recent developer notes hinting at more Natlan characters in the pipeline for 2025, this artifact set is expected to remain relevant throughout the year.

Farming Strategy for Optimal Results

When farming Obsidian Codex artifacts, consider these tips to maximize efficiency:

Stat Priority Main Characters Alternative Characters
Sands ATK% / EM ER%
Goblet Pyro DMG% ATK%
Circlet CRIT DMG% CRIT Rate%

Substats to prioritize:

  • CRIT DMG% (primary focus due to 4-piece set bonus)

  • ATK%

  • Energy Recharge

  • Elemental Mastery

💡 Pro Tip: With the Artifact Crafting system now fully upgraded in 2025, don't forget to convert your unwanted 5-star artifacts into Obsidian Codex pieces at the crafting table!

Comparing to Other Sets

The Obsidian Codex set has effectively outclassed the Marechaussee Hunter set for many characters, despite their somewhat different mechanics. The raw numbers tell the story:

  • Obsidian Codex: 15% all DMG + 40% CRIT Rate (conditional)

  • Marechaussee Hunter: 15% Normal/Charged Attack DMG + 36% ATK (conditional)

For Natlan DPS characters, the math clearly favors Obsidian Codex, especially considering how the CRIT Rate bonus allows for more flexible artifact building.

Future Prospects

As Genshin Impact continues to expand through 2025, the Obsidian Codex set remains a cornerstone for Natlan character builds. With the upcoming Natlan storyline expansions announced for Version 5.7 and beyond, players can expect more characters who will benefit from this powerful artifact set.

The Obsidian Codex set stands as a testament to HoYoverse's evolving design philosophy, integrating regional mechanics (Nightsoul's Blessing) directly into artifact functionality. Like a fine wine that improves with age, this artifact set has only grown in value as more compatible characters have been released.

Whether you're building Mualani, Kinich, Itzli, or preparing for future Natlan characters, investing time in farming the perfect Obsidian Codex set is undoubtedly one of the wisest uses of your resin in Genshin Impact's current meta. Happy farming, Travelers! 🔥
