Here’s the thing about weekly boss farming in 2025—it’s become the biggest bottleneck in character progression. We’re talking 18 specific materials plus 5 million Mora just to triple-crown one character’s talents. Factor in weekly lockouts, that brutal three-way RNG, and Dream Solvent being as rare as it is? Yeah, poor planning here can set your roster development back by literal months.
The math is pretty unforgiving: 33% Dream Solvent drop rate, first three weekly bosses at 30 Original Resin each (then it jumps to 60). Smart planning versus random farming? We’re talking about shaving months off your character building timelines.
For keeping your farming schedule consistent, Genesis Crystal discount code options from BitTopup offer solid value with competitive pricing and quick delivery—because missing farming windows due to resin shortages is just painful.
The Weekly Boss Economy (And Why It’s Brutal)
Resin Reality Check
Weekly rewards reset every Monday at 4:00 AM server time. Those first three claims? 30 Original Resin each. After that? 60 Resin per fight—literally double the cost. This makes selective farming absolutely critical.
At World Level 8, you’re averaging 2.4 talent materials per boss fight. Usually lands between 2-3 drops. With perfect RNG and correct boss targeting, you’re looking at 7.5 weeks minimum for those 18 materials.
Here’s how the economics break down:
Perfect RNG scenario: 7.5 weeks for 18 materials
Average RNG (mixed drops): 12-15 weeks
Poor RNG (wrong materials): 20+ weeks without conversions
Not exactly encouraging, right?
Drop Rates That’ll Make You Cry
Dream Solvent sits at a 33% drop rate regardless of World Level—it’s your main RNG safety net. You’ll average one Dream Solvent every three fights, which translates to about 15-20 conversions monthly from regular farming.
Weapon Billets? 12% drop rate per fight. Low enough that you need to factor billet needs into your weekly rotation if you’re relying on F2P weapon crafting.
The Complete Boss Lineup (And What They Actually Drop)
The Old Guard
Dvalin: Still dropping Plume/Claw/Sigh for Diluc, Venti, and Albedo. Single-player encounter, moderate difficulty at best.
Andrius: Ring/Spirit Locket/Tail of Boreas for Razor, Chongyun, and Ganyu. Open-world fight with that annoying Cryo immunity.
Childe: Tusk/Shard/Shadow materials for Zhongli, Xiao, and Hu Tao. Three-phase fight that’s mechanically intensive but manageable once you learn the patterns.
Azhdaha: Crown/Branch/Scale for Ayaka, Kazuha, and Yelan. Features those elemental infusions that demand strong shields—learned that the hard way.
The New Powerhouses
The Knave (Arlecchino): Drops Silken Feather/Denial and Judgment/Fading Candle for Fontaine characters. Hands down the most mechanically demanding fight with precise dodge timing that’ll humble you.
All-Devouring Narwhal: Provides Lightless Mass/Silk String/Eye materials for late Fontaine roster. Those void mechanics and phase transitions keep you on your toes.
Lord of Eroded Primal Fire: Drops Eroded Horn/Sunfire/Scale-Feather for Natlan characters, including upcoming Lauma. Introduces that Attrition debuff that completely bypasses shields—fun times.
The pattern’s pretty clear: newer bosses show regional clustering. Fontaine and Natlan bosses gate the majority of current meta characters, making them significantly higher priority than those legacy fights.

Character Demand Analysis (The Real Priority List)
Materials Everyone’s Going to Need
The Game Before the Gate materials are gating both Flins (Ascended Sample: Queen) and Ifa (Ascended Sample: Rook)—making this the highest priority boss for 2025 character prep. Two major releases needing these materials? Start stockpiling now.
Lord of Eroded Primal Fire materials serve Lauma (Eroded Scale-Feather) and other Natlan characters. Second-highest priority for future-proofing, though that Attrition mechanic is going to challenge shield-dependent teams.
Scaramouche continues gating Wanderer, Nahida, and Alhaitham. Despite its age, the breadth of character dependencies keeps it relevant.
The Overlap Game
Raiden puppet boss materials serve late Inazuma and early Sumeru characters—natural farming synergies there. Fontaine bosses show less overlap, though. The Knave and Narwhal serve pretty distinct character pools, requiring more targeted farming.
Priority Framework (By Player Stage)
New Player Roadmap (AR 40-55)
Quick Challenge feature lets you access bosses immediately, regardless of story progression. Here’s your focus order:
Current main DPS talent materials
Primary support character needs
Widely-used characters (Zhongli, Kazuha, Bennett)
Future-proofing only after your core team’s solid
Mid-Game Balance
You’re juggling immediate roster needs with selective future-proofing. Target 2-3 specific upcoming characters rather than broad stockpiling. That First-Time Clear Reward gives you one of each material from newly defeated bosses—nice little bonus.
Endgame Focus (AR 55+)
Heavy priority on newest bosses for future character preparation. With established rosters, you’re shifting focus to long-term resource accumulation:
Newest weekly bosses (Fontaine/Natlan)
Dream Solvent accumulation
Billet farming for weapon diversity
Crown conservation for optimal characters
Dream Solvent Strategy (Your RNG Insurance)
When to Convert
Convert immediately for current character builds, especially with unfavorable drop distributions. Save conversions when you’ve got 6+ weeks available for natural farming. With only 4-5 monthly supply, you need strategic usage over immediate conversion.
Keep a 10-15 Dream Solvent reserve for upcoming releases. This buffer allows immediate talent upgrades without waiting for additional farming cycles.
Future Prep
Upcoming releases like Mavuika require entirely new weekly boss materials. Plan for 6-9 conversions per new character for RNG mitigation.
Access and Optimization Tips
Quick Challenge System
AR 40+ bypasses story quest requirements through the Adventurer Handbook. Access Fontaine/Natlan bosses immediately regardless of Archon Quest progression—massive time saver for new players.
World Level 8 averages 2.4 materials versus WL7’s 2.1. Minimal difference means don’t delay farming. Co-op’s available for all bosses except Dvalin.
Weekly Schedule Management
Plan your rotation before Monday reset, prioritizing those three 30-resin discount claims on highest-value targets. Each extra fight costs 60 resin—equivalent to three artifact domains.
Spread fights across multiple days to avoid resin overflow. Adjust during events offering competing priorities or bonus weekly boss rewards.
Future-Proofing Strategy
Confirmed Upcoming Materials
Flins (Version 6.0): Ascended Sample: Queen from The Game Before the Gate
Lauma (Version 6.0): Eroded Scale-Feather from Lord of Eroded Primal Fire
Ifa: Ascended Sample: Rook from The Game Before the Gate
Mavuika (Version 5.3): New unreleased weekly boss material
Long-term Planning
Version updates introduce new weekly bosses every 2-3 major patches. Plan stockpiling around confirmed character schedules, focusing 2-3 patches ahead. That Nod-Krai region expansion will introduce additional bosses too.
Target 50-75 materials per boss type for comprehensive future-proofing. This allows immediate triple-crown capability for 2-3 characters per material type.
Common Mistakes (That’ll Cost You Months)
Optimization Errors
Overfarming legacy bosses out of habit rather than strategic need? Pure resin waste. Evaluate your character pipeline monthly and redirect toward higher-value targets. Don’t farm easier bosses just because—resin cost’s identical regardless of clear time.
Hoarding Dream Solvent while struggling with RNG represents efficiency loss. Use conversions strategically, but don’t over-save at the expense of current progression.
Fighting more than three weekly bosses per week rarely provides better value than alternative farming. Unless immediate character needs justify that 60-resin premium cost.
Advanced Development Strategies
Multi-Character Coordination
Coordinate farming with banner schedules and acquisition plans. Focus on materials for intended pulls rather than broad speculation. Consider material sharing when planning builds—characters requiring the same materials develop simultaneously.
Investment Analysis
Evaluate triple-crown ROI versus broader roster depth. That 18-material requirement per character represents significant opportunity cost that might be better distributed. Crown scarcity (one per version) often constrains optimal talent investment more than weekly materials anyway.
Adjust priorities based on Spiral Abyss rotations and meta shifts. Monitor tier lists and usage statistics to identify sustained long-term value versus temporary meta relevance.
FAQ
Which weekly boss should I prioritize first in 2025? New players: bosses required by your current main DPS. Veterans: The Game Before the Gate and Lord of Eroded Primal Fire for upcoming Natlan characters. Use Quick Challenge at AR 40+ for immediate access.
How many weekly bosses should I fight per week? Exactly three for that 30-resin discount optimization. Additional fights cost 60 resin each—rarely better value than artifact domains. Only exceed three for immediate character building needs.
What are the most valuable drops for new characters in 2025? The Game Before the Gate materials (Flins and Ifa) and Lord of Eroded Primal Fire materials (Lauma). These gate multiple confirmed releases, making them essential for future-proofing.
Should I use Dream Solvent or farm specific bosses? Use Dream Solvent for immediate needs or after 4+ weeks of unfavorable RNG. Save when you’ve got 6+ weeks available for natural farming. Maintain a 10-15 reserve for emergencies.
How do I calculate weekly boss resin efficiency? First three bosses: 30 resin, 2.4 materials average (0.08 materials/resin). Additional fights: 60 resin, same drops (0.04 materials/resin)—significantly less efficient.
What materials will upcoming characters need? Flins: Ascended Sample: Queen, Lauma: Eroded Scale-Feather, Ifa: Ascended Sample: Rook, Mavuika: new unreleased materials. Focus The Game Before the Gate and Lord of Eroded Primal Fire.
