Understanding Furina’s Kit: The Foundation of Smart Weapon Choices
Here’s the thing about Furina that catches a lot of players off guard—her weapon selection isn’t just about raw damage. You’re juggling four critical priorities that all compete for your attention: Max HP for her Elemental Skill and Burst scaling, Energy Recharge to keep that expensive 60-cost Burst flowing, CRIT stats for respectable Sub-DPS numbers, and hitting that sweet 40,000 HP threshold for maximum team buffs from her A4 Passive.
Her Salon Members are constantly draining party HP above 50% to ramp up damage by up to 140%. This mechanic is what makes weapons like Splendor of Tranquil Waters absolutely shine—they’re designed around these HP fluctuations.
Energy Recharge gets complicated fast. Solo Hydro teams (C0-C3) demand 200-220%, drop that to 180-210% with one Hydro teammate, and 150-170% with two Hydro characters. C4 changes everything—those 4 Energy ticks every 5 seconds slash requirements to 140-160%, 130-150%, and 100-120% respectively. Each Favonius weapon proc in your team? That’s another 20-30% reduction across the board.

Splendor of Tranquil Waters: When Signature Weapons Actually Matter
Let’s be honest—most signature weapons feel like luxury purchases. Splendor breaks that mold.
542 Base ATK and 88.2% CRIT DMG form the foundation, but the dual-stack passive system is where things get interesting. You’re looking at 8% Elemental Skill DMG per stack (capping at 24%) whenever the wielder’s HP shifts, plus 14% Max HP per stack (28% maximum) when any party member’s HP fluctuates. Both effects last 6 seconds, and in healer teams? You’re maintaining near-permanent uptime.
R5 refinement doubles everything—16% per stack for 48% Skill DMG, 28% per stack for 56% Max HP. That’s a clean 100% improvement over R1, which explains why some theorycrafters get genuinely excited about this weapon’s scaling potential.
Testing consistently shows 15-25% higher Elemental Skill damage versus alternatives when passive conditions are met. The CRIT DMG substat also simplifies reaching that optimal 1:2 ratio without artifact gymnastics.
5-Star Alternatives: When Splendor Isn’t an Option
S-Tier Territory: Primordial Jade Cutter leads the pack among alternatives, and honestly? It’s closer than you’d expect. 44.1% CRIT Rate plus an unconditional 20% HP bonus maintains 85-95% of Splendor’s damage output with superior consistency. No passive management, no team composition requirements—just reliable performance.
Key of Khaj-Nisut takes a different approach with 66.2% HP substat plus 20% passive (86.2% total) and party-wide EM buffs. Perfect for reaction teams where that extra EM actually matters.
A-Tier Options: Light of Foliar Incision and Mistsplitter Reforged function as powerful stat sticks—88.2% CRIT DMG and 44.1% CRIT Rate respectively. They won’t optimize around Furina’s kit, but raw stats carry weight. Uraku Misugiri offers 24% Elemental Skill DMG (48% with Geo Constructs) for those running specialized compositions.
For reliable crystal acquisition during limited banners, Splendor of Tranquil Waters fund management through BitTopup ensures optimal pity planning with competitive rates and instant delivery.
4-Star Champions: Budget Excellence That Competes
Here’s where Furina gets really interesting from a value perspective.
Festering Desire (R5) absolutely dominates the 4-star space. 45.9% ER, 32% Elemental Skill DMG, and 12% Elemental Skill CRIT Rate—this thing often outperforms 5-star weapons when ER requirements climb high. The catch? It’s event-exclusive from Version 1.2. If you missed it, you’re out of luck.
Fleuve Cendre Ferryman becomes your best F2P friend via Fontaine fishing. 45.9% ER, 16% Elemental Skill CRIT Rate, and a 32% temporary ER boost after Skill usage. Performance sits at 95-98% of Festering Desire with guaranteed R5 availability for everyone.
Wolf-Fang (Battle Pass) offers 27.6% CRIT Rate and 16% Elemental Skill/Burst DMG for offensive builds. Favonius Sword provides 61.3% ER and team energy generation—it solves energy problems for multi-element compositions despite lower personal damage output.
Refinement Strategy: Where to Spend Your Resources
Priority Order (and this matters more than most guides admit):
Fleuve Cendre Ferryman (R1→R5): Free fishing materials, 16% Skill CRIT Rate at R5 vs 8% at R1
Festering Desire: Event-exclusive, can’t be refined post-event
Wolf-Fang: Battle Pass provides guaranteed refinement path
Splendor R1→R2: Noticeable improvement, but higher refinements show diminishing returns
Expert consensus consistently prioritizes Furina’s C1/C2 constellations over weapon refinements. The team-wide benefits and competitive 4-star options make this a no-brainer for most accounts.
Performance Reality Check: Numbers That Matter
High ER Scenarios (200%+ requirement):
Festering Desire (R5): 100% baseline
Fleuve Cendre Ferryman (R5): 95-98%
Splendor of Tranquil Waters: 90-95%
Wait, Splendor performs worse at high ER requirements? Exactly. This is why understanding your team composition matters more than chasing the shiniest weapon.
Low ER Scenarios (150% requirement):
Splendor of Tranquil Waters: 100% baseline
Primordial Jade Cutter: 90-95%
Key of Khaj-Nisut: 85-90%
Testing methodology accounts for realistic passive uptime, team synergy effects, and Burst maintenance across single/multi-target encounters with varying duration.
Common Mistakes (That I See Constantly)
Most frequent error? Ignoring ER requirements for pure damage stats, then wondering why Burst uptime feels terrible. HP% investment beyond the 40,000 threshold provides minimal returns versus CRIT stats. Weapon refinements before C1/C2 constellations represent poor resource allocation—I can’t stress this enough.
Artifact synergy gets overlooked too. HP% Goblets with high-HP weapons create diminishing returns; Hydro DMG% becomes more valuable. ER% Sands with ER weapons can exceed requirements unnecessarily. Flat HP substats actually provide meaningful value due to HP scaling mechanics.
Acquisition Strategy: Planning Your Pulls
Splendor appears exclusively on limited weapon banners (versions 4.2, 4.7, 5.4). Investment priority should follow this order: character acquisition → C1/C2 constellations → signature weapons. The weapon banner requires both featured weapons to provide roster value due to that brutal 240-pull guarantee system.
F2P players should prioritize character banners and utilize excellent F2P options. Light spenders can consider weapon banners after securing desired characters, with Battle Pass providing middle-ground investment through guaranteed refinement paths.

Can Furina use 4-star weapons effectively? Absolutely. Festering Desire (R5) often outperforms 5-stars at high ER requirements. Fleuve Cendre provides 95-98% performance with permanent availability. Wolf-Fang offers strong offensive potential when ER needs are met through artifacts.
