Genshin Impact Version 6.3 launches January 14, 2026, introducing Columbina as a 5-star Hydro Catalyst. This guide covers optimized farming routes for her ascension materials: 46 Radiant Antler from Frostnight Herras, 168 Winter Icelea specialties, and Moonlight talent books from Lightless Capital. Master resin allocation, domain unlocks, and time-efficient routes for Day 1 preparation.
Understanding Nod Krai Domains
Domain Types and Locations
Nod Krai (added Version 6.0, September 10, 2025) spans three areas: Lempo Isle, Hiisi Island, and Paha Isle. Three primary domains serve distinct purposes:
Lightless Capital (Lempo Isle): Moonlight talent books, Monday/Thursday/Sunday rotation
Lost Mooncourt (Hiisi Island): Hydro-optimized artifact sets
Frostladen Machinery (Paha Isle): Weapon ascension materials
Each costs 20 Original Resin per clear. Condensed Resin doubles rewards for 40 Resin.
Difficulty Tiers and Rewards
Four difficulty levels unlock via Adventure Rank:
Level I: AR 22
Level IV: AR 45 (required for efficient farming)
Level IV guarantees 2-3 Philosophies of Moonlight per run vs. Level I's 0-1 drops—a 300% efficiency increase. Always farm Level IV.
Unlock Requirements
Access requires Archon Quest Prologue Act III completion (AR 22+).
Lightless Capital route: Nasha Town waypoint → Kuuhenki cliff top → lift to first floor → Statue of the New Moon → path toward Northern Training Ground → glide left to domain entrance near Clink-Clank Krumkake Craftshop. First-time navigation takes 8-10 minutes.
Columbina Material Requirements
Ascension Materials (Level 1-90)
Gemstones: 1 Varunada Lazurite Sliver, 9 Fragments, 9 Chunks, 6 Gemstones (from Hydro Hypostasis, Oceanid, or weekly bosses at 30 Resin for first three weekly clears)
Boss Materials: 46 Radiant Antler (Frostnight Herras drops 2-3 per kill, requires 15-23 kills)
Local Specialties: 168 Winter Icelea (48-hour respawn, 60-70 per collection cycle, needs three full cycles)
Common Drops: 36 Slime Condensate, 96 Slime Secretions, 129 Slime Concentrate
Talent Materials (Per Talent to Level 10)
9 Teachings of Moonlight
63 Guide of Moonlight
114 Philosophies of Moonlight
18 Slime Condensate, 66 Slime Concentrate
3 Crown of Insight (limited event/tree rewards)
Lightless Capital runs: 19-29 Level IV clears per talent using Condensed Resin.
Total Resin Cost
Gemstones: 90 Resin weekly (three bosses), 4-6 weeks total Talent Books: 1,140-1,740 Resin for three talents (6-10 days exclusive farming) Weapon Materials: 600-800 Resin
Reserve 15-20 Fragile Resin for acceleration. Each Fragile Resin = 60 Original Resin (three domain runs).

Optimized Farm Routes
30-Minute Daily Route
Phase 1 - Radiant Antler (10-12 min): Start northern Hiisi Island waypoint, circle clockwise for 2-3 Frostnight Herras spawns. Yields 4-9 Radiant Antler daily.
Combat tip: Use Pyro DPS (Bennett, Kaeya) for Cryo shield breaking. Electro/Hydro supports trigger reactions.
Phase 2 - Winter Icelea (15-18 min): Collect 25-30 plants across three Hiisi zones: northern frost fields, central valley, southern coast.
Phase 3 - Slimes: Farm Hydro/Cryo Slimes in waterways during remaining time.
Weekend Marathon Route
Saturday morning:
Six Condensed Resin runs at Lightless Capital (120 Resin, 30-40 min) = 12-18 Philosophies
Full Winter Icelea collection across all islands (45-60 min) = 60-75 specialties
Extended Frostnight Herras farming (4-6 encounters) = 8-18 Radiant Antler
Three weekly boss clears (90 Resin) for gemstones
Total time: 2-3 hours for comprehensive weekly progress.
Resin-Free Farming
Focus on overworld materials:
Frostnight Herras: 10-12 min per cycle, 12-hour respawn. Morning + evening runs = 8-18 Radiant Antler daily. Completes 46-antler requirement in 3-6 days.
Winter Icelea: 48-hour respawn. Establish Monday/Wednesday/Friday collection schedule. Three cycles = 180-225 specialties (exceeds 168 requirement).
World Level Optimization
World Level 8: Guaranteed 3 Radiant Antler per Frostnight Herras kill (16 kills total) World Level 6-7: 2-3 drops, 60% for higher amount (19-23 kills needed)
Maintain maximum World Level for 50% efficiency gain despite harder combat.
Best Team Compositions
Speedrun Teams (Sub-60 Second Clears)
Lightless Capital: Hu Tao/Ayaka (DPS) + Kazuha (amplification) + Bennett (buff) + Xingqiu/Yelan (Hydro). Clear time: 45-55 seconds.
Rotation: Bennett burst → Kazuha crowd control → Xingqiu Hydro → DPS burst combo.
Lost Mooncourt: Diluc/Klee/Yoimiya (Pyro DPS) + Zhongli (shield) + Kazuha + Bennett. Clear time: 50-65 seconds.
Frostladen Machinery: Raiden Shogun + Xiangling (Overloaded) + Kazuha + Bennett. Clear time: 40-50 seconds.
F2P Teams
Core: Traveler (Anemo) + Kaeya + Lisa + Barbara. Clear time: 90-120 seconds.
Improved: Add Xiangling (Spiral Abyss Floor 3 reward) + Fischl (events). Clear time: 60-75 seconds.
Weapon priority: The Catch for Xiangling (fishing reward), Prototype Rancour for physical DPS (craftable).
Element Counters
Lightless Capital: Two Pyro characters for Cryo shields + 25% ATK resonance
Lost Mooncourt: Kaeya/Rosaria (Cryo) + Pyro for Melt reactions, 40-50% faster shield breaks
Frostladen Machinery: Fischl/Raiden (Electro) + Xingqiu (Hydro) for Electro-Charged AoE
Support Optimization
Bennett: Level 70, Talent 6 burst, HP/Energy Recharge artifacts. Highest value investment.
Kazuha: Full Elemental Mastery + Viridescent Venerer set. 90% max potential with minimal substats.
Xingqiu/Yelan: Sacrificial Sword/Favonius Warbow, prioritize Energy Recharge over crit stats.
Resin Management
Condensed vs Original Resin
Condensed Resin: 40 Original Resin + 1 Crystal Core, max storage 5 units. Halves time investment with identical rewards.
Use for: Talent books, weapon materials (guaranteed drops) Avoid for: Artifact hunting (more reward rolls with individual runs)
Daily cap: 180 Resin regenerates at 1 per 8 minutes. Craft Condensed during sleep/work, execute concentrated sessions during active play.
Daily Allocation Strategy
Monday/Thursday/Sunday: 120 Resin to Lightless Capital (six Condensed runs) Other days: Weapon materials or hold for Columbina release Weekly: 90 Resin for three weekly bosses (complete Monday)
Avoid premature artifact farming before optimal builds are confirmed.
Fragile Resin Investment
Each Fragile Resin = 60 Original Resin (three domain runs). Average accumulation: 30-40 per version.
Best use: Talent book farming on Lightless Capital days. 10 Fragile Resin = 30 runs = 60-90 Philosophies (5-7 day acceleration).
Avoid: Artifact farming (RNG substats make inefficient). Prioritize talents and weapon ascension first.
Reserve 15-20 Fragile Resin for Columbina's release week (900-1,200 bonus Resin for Day 1 completion).
Materials Per Resin Analysis
Lightless Capital: 2.5 Philosophies per 20 Resin average. One talent to Level 10 = 912 Resin (5.1 days max daily allocation).
Weekly Bosses: 0.33-0.5 gemstone fragments per 30 Resin. Complete gemstones = 540-720 Resin over 4-6 weeks.
Weapon Domains: 2-3 highest-tier materials per 20 Resin. Complete ascension = 600-800 Resin.
Drop Rates and RNG
Statistical Probabilities
Frostnight Herras:
World Level 8: 3 Radiant Antler guaranteed (16 kills for 46 total)
World Level 6-7: 2-3 drops, 60% for 3 (19-23 kills needed)
Lightless Capital: Minimum 2 Philosophies, 40% for third. 100 runs average = 240 Philosophies (two talents to Level 10).
Weekly Bosses: 2-3 gemstone fragments, equal probability across types. 1-in-3 odds for Varunada Lazurite. Dream Solvent enables 1:1 conversion.
Winter Icelea: Zero RNG. Fixed spawns, guaranteed 48-hour respawns.
Pity Systems
Domains guarantee minimum drops (no completely wasted runs). Weekly bosses use Dream Solvent as soft pity for gemstone conversion.
Artifact domains lack pity protection—delay until character development completes.
Battle Pass provides guaranteed supplements: talent books, weapon materials, Fragile Resin.
Common Mistakes
Resin Wastage
Cap overflow: 180 Resin fills in 24 hours. Skipping daily farming loses 180 Resin permanently. Two-week inconsistency wastes 1,260-2,520 Resin (63-126 domain runs).
Wrong difficulty: Level III vs Level IV sacrifices 30-40% efficiency. Always farm Level IV at AR 45+.
Premature artifacts: Investing 1,000+ Resin before completing talents delays character functionality by 5-7 days.
Ignoring Condensed Resin: Twelve individual runs vs six Condensed wastes 30-40 minutes daily for identical rewards.
Weekly Boss Neglect
Skipping weekly resets loses 30-Resin discount permanently (subsequent clears cost 60 Resin). Complete three bosses every reset for gemstone progression and Dream Solvent accumulation (1 per 2-3 bosses average).
Team Composition Errors
Elemental mismatch (Cryo DPS in Cryo domains) extends clears from 60 to 180+ seconds
Insufficient Energy Recharge (need 180-220% on Bennett/Xingqiu/Xiangling) delays rotations by 20-30 seconds
Single-target DPS in wave domains underperforms vs AoE specialists
No shield-breaking capability: enemies with shields take 90% reduced damage
Advanced Tips
Animation Canceling
Hu Tao Charged Attack: Dash-cancel increases attack frequency 30-40% Burst skipping: Character swap immediately after burst activation saves 2-3 seconds (8-12 seconds per rotation) Movement optimization: Position near next wave spawn during final kills (saves 5-8 seconds) Skill queuing: Input buffering during animations enables frame-perfect execution
Total time reduction: 10-15 seconds per domain run.
Co-op Coordination
Specialized roles achieve 20-30% faster clears:
1 player: Primary DPS
2 players: Elemental support/reactions
1 player: Healing/buffing
Voice coordination for burst synchronization (Bennett → Kazuha → DPS) increases effective DPS 40-50%.
Designate burst caller to prevent overlapping buffs. Build dedicated farming groups vs random matchmaking.
