Genshin Artifact Transmuter Guide: Craft vs Farm Math 2025

The Artifact Transmuter (Version 5.0) lets you craft Obsidian Codex pieces with selected main stats and two guaranteed substats using Sanctifying Elixirs. But crafting Goblets costs 4 Elixirs (45,252+ resin), while domain farming relies on RNG. This guide breaks down the math to optimize your artifact strategy.

Sanctifying Elixir Acquisition

Artifact Extraction (sacrifice level 4+ 5-Star artifacts until 100% progress):

  • On-set EM/ER Sands with double CRIT: 11,313 resin per Elixir (most efficient)
  • On-set elemental Goblets with double CRIT: 14,014 resin per Elixir
  • On-set CRIT Circlets with 1 CRIT + 1% stat: 18,855 resin per Elixir

Limited Sources:

  • Tablet of Tona: 5 Elixirs (1 per 10 levels to level 50)
  • Obsidian Fragments: 3 Elixirs (combine yellow, green, azure into Obsidian Rings)
  • Battle Pass level 26: 1 Elixir per cycle
  • Weekly Extraction: 1 Elixir per 6 weeks

Crafting Process

  1. Access Transmuter in Inventory Gadget tab
  2. Select artifact set (Obsidian Codex)
  3. Choose piece type
  4. Select main stat
  5. Choose up to 2 substats (3rd and 4th randomize)
  6. Confirm with required Elixirs

Crafted artifacts start at level 0 with 3 substats. Version 5.5 guarantees 2 upgrades for minor affixes.

  • 4-Piece: Consume 1 Nightsoul point for +40% CRIT Rate (6s, once per second)

Transmuter Efficiency Math

Elixir Cost Per Piece

Using optimal method (11,313 resin per Elixir):

  • Flower: 1 Elixir = 11,313 resin
  • Feather: 1 Elixir = 11,313 resin
  • Sands: 2 Elixirs = 22,626 resin
  • Goblet: 4 Elixirs = 45,252 resin
  • Circlet: 3 Elixirs = 33,939 resin

Timeline Barriers

Crafting 1 Goblet (4 Elixirs) = 24 weeks via weekly Extraction alone. Limited sources (Tablet, Fragments, Battle Pass) are critical for practical use.

Hidden Costs

  • Artifact fodder: 30,000-50,000 EXP per sacrificed piece
  • Mora: 15,000-25,000 per piece
  • Opportunity cost of sacrificing usable artifacts

Domain Farming Efficiency

Drop Rates (World Level 8)

20 resin per run guarantees 1+ 5-Star artifact. Piece type: 20% each.

Main Stat Probabilities:

  • Flower/Feather: Fixed (100%)
  • Sands: EM/ER ~10% each
  • Goblet: Elemental DMG ~5% each
  • Circlet: CRIT Rate/DMG ~10% each

Average Resin Costs

Goblet with specific elemental DMG:

  • Probability: 20% × 5% = 1%
  • Average: 100 runs = 2,000 resin (no substat consideration)

CRIT Circlet:

  • Probability: 20% × 10% = 2%
  • Average: 50 runs = 1,000 resin

EM/ER Sands:

  • Probability: 20% × 10% = 2%
  • Average: 50 runs = 1,000 resin

Condensed Resin doubles rewards per run, halving time but not total resin cost.

Head-to-Head Comparison

Comparison of domain farmed vs transmuted Obsidian Codex artifacts in Genshin Impact

By Piece Type

Flower/Feather: Domain wins. Fixed main stats = 20% probability = 100 resin average vs 11,313 resin transmuter.

Common Sands (ATK%/HP%/DEF%): Domain wins. Frequent drops vs 22,626 resin transmuter.

EM/ER Sands: Competitive. Domain averages 1,000 resin vs 22,626 transmuter with 2 guaranteed substats. Transmuter wins if you need specific substats (double CRIT).

Elemental DMG Goblet: Transmuter shows potential. Domain averages 2,000 resin vs 45,252 transmuter, but guaranteed substats improve value for min-maxing.

CRIT Circlet: Domain typically wins. 1,000 resin average vs 33,939 transmuter, unless you need extremely specific substat combos.

Substat Quality

Transmuter guarantees 2 desired substats + 2 guaranteed upgrades (Version 5.5). Domain pieces often roll flat HP/DEF/ATK. But 3rd/4th substats and upgrade distribution remain RNG—crafted pieces can still roll poorly.

Time Investment

Domain farming: immediate results, multiple pieces daily. Transmuter: weeks/months to accumulate Elixirs.

Domain farming suits multi-character building. Transmuter targets single pieces with precision.

When to Use Transmuter

Optimal Scenarios:

  • Completing near-perfect sets (missing 1 specific Goblet/Circlet)
  • Targeting rare combos (elemental Goblet + double CRIT substats)
  • Endgame min-maxing with surplus artifacts

Best for:

  • Veterans with completed rosters
  • Players who refresh resin regularly
  • Converting accumulated fodder into targeted upgrades

When to Farm Domains

Advantages:

  • Building complete sets from scratch
  • Equipping multiple characters simultaneously
  • Lower opportunity cost with immediate value
  • Volume increases probability of exceptional pieces

Best for:

  • New players starting Obsidian Codex farming
  • Multi-set farming efficiency
  • Broader roster development

Sanctum of Rainbow Spirits drops only Obsidian Codex, ideal for focused farming.

Common Misconceptions

Myth: Transmuter always saves resin Reality: Only specific scenarios justify investment. Flowers, Feathers, common Sands are cheaper via domains.

Myth: Full substat control Reality: Only 2 substats selected. 3rd/4th randomize, upgrades follow RNG. Version 5.5's 2 guaranteed upgrades help but don't eliminate variance.

The Numbers Show: Efficiency depends entirely on piece requirements and player circumstances. No universal answer.

Expert Optimization Strategies

Hybrid Approach

Phase 1 (Weeks 1-4): Domain farm for 20-30 base pieces. Target Flowers, Feathers, common Sands.

Phase 2 (Week 5): Analyze gaps. Identify missing pieces justifying transmuter investment.

Phase 3 (Weeks 6+): Use accumulated Elixirs for specific missing pieces with required main stats/substats.

Elixir Optimization

Prioritize sacrificing on-set EM/ER Sands with double CRIT (11,313 resin per Elixir). Avoid Goblets/CRIT Circlets unless equivalent efficiency.

Collect Limited Sources:

  • Tablet of Tona: 5 Elixirs
  • Obsidian Fragments: 3 Elixirs
  • Battle Pass: 1 Elixir per cycle

Total: 8-9 Elixirs = 2 Goblets or 1 Goblet + 1 Circlet without artifact sacrifice.

Long-Term Planning

Complete 5-piece set requires: 1 (Flower) + 1 (Feather) + 2 (Sands) + 4 (Goblet) + 3 (Circlet) = 11 Elixirs

At 11,313 resin per Elixir = 124,443 resin = 207 days natural regeneration.

Hybrid approach (domains for common pieces, transmuter for rare) provides superior efficiency.

Real Gameplay Examples

Mualani: Transmuter Method

Resources: 8 Elixirs (5 Tablet + 3 Fragments), 15 off-set EM Sands with double CRIT

Week 1-2: Sacrifice Sands → 1 Elixir (total: 9) Week 3: Craft Hydro Goblet (4 Elixirs, CRIT Rate + CRIT DMG) Week 4: Craft CRIT Rate Circlet (3 Elixirs, CRIT DMG + ATK%) Week 5-8: Domain farm Flower, Feather, ATK% Sands

Result: Complete set in 8 weeks with guaranteed main stats and favorable substats on hardest pieces.

Kinich: Domain Method

Week 1-4: 6 Condensed runs daily (168 total runs)

Acquired:

  • 34 Flowers (8 with double CRIT)
  • 33 Feathers (6 with double CRIT)
  • 35 Sands (4 ATK% with CRIT)
  • 32 Goblets (1 Dendro DMG with CRIT)
  • 34 Circlets (2 CRIT Rate with CRIT DMG)

Result: Usable 5-piece set in 4 weeks plus surplus for other characters.

Analysis: Transmuter = superior substat quality, 8 weeks, pre-accumulated resources. Domain = faster completion, acceptable quality, broader roster value.

FAQ

How does the Artifact Transmuter work? Craft specific 5-Star pieces by selecting set, piece type, main stat, and 2 substats. Costs 1-4 Sanctifying Elixirs per piece. Unlock via Chapter 4 Embattle (25 5-Star Artifacts). Crafted pieces start level 0 with 3 substats and 2 guaranteed upgrades (Version 5.5).

Is crafting or farming cheaper? Domain farming wins for Flowers (100 resin avg vs 11,313), Feathers (100 vs 11,313), common Sands (1,000 vs 22,626). Transmuter becomes competitive for rare Goblets with specific substats (2,000 domain avg vs 45,252 transmuter with guarantees). Depends on piece type and substat needs.

How many Elixirs per artifact? Flower/Feather: 1, Sands: 2, Circlet: 3, Goblet: 4. Each Elixir = 11,313-18,855 resin (optimal: EM/ER Sands with double CRIT = 11,313).

What's the resin efficiency? Optimal Elixir farming: 11,313 resin per Elixir. Goblet minimum: 45,252 resin. Exceeds domain efficiency except for rare main stat + substat combos requiring thousands of domain runs.

How to unlock Transmuter? Complete Chapter 4 Embattle (Adventurer Handbook) by obtaining 25 5-Star Artifacts. Access via Inventory Gadget tab. Available since Version 5.0 (August 28, 2025).

Which method gives better substats? Transmuter guarantees 2 selected substats + 2 upgrades (Version 5.5), better control than domains. But 3rd/4th substats and upgrade distribution remain RNG. Domain volume increases odds of exceptional pieces. Transmuter wins for targeted single-piece optimization; domains win for complete set building through statistical variance.
