Character Overview: What Makes These Two Tick
Kit Analysis and Core Abilities
Let’s talk numbers first. Xianyun’s A4 Passive is where the magic happens—she slaps on an Additive Base DMG Bonus to plunging attack shockwaves equal to 200% of her ATK. That caps out at 9,000 damage per plunge at C0 (18,000 at C2, which is honestly wild). This flat damage gets applied before CRIT and DMG% multipliers kick in, making it stupidly effective.
Faruzan? She’s all about that multiplicative scaling. Her Elemental Burst delivers 30% Anemo RES Shred and 32.4% Anemo DMG Bonus at Talent Level 10. Her 4th Ascension Passive throws in some flat damage based on 32% of her Base ATK, and her C6—oh boy, her C6 adds 40% Anemo CRIT DMG. It’s like giving Xiao a damage steroid.
Role Definition in Xiao Teams
Here’s where things get interesting. Xianyun isn’t just a damage buffer—she’s a hybrid support-healer whose healing actually follows your active character around. Perfect for Xiao’s mobile playstyle and that annoying HP drain, right? Plus, this creates insane synergy with Furina, whose Fanfare stacks go absolutely bonkers when team HP fluctuates.
For players looking to maximize their team potential, Xiao banner prep crystals top up through BitTopup ensures you have the primogems needed for optimal constellation investments, with competitive pricing and instant delivery that keeps your pulling schedule on track.
Faruzan’s the pure Anemo specialist. She needs 250-300% Energy Recharge pre-C6 (yeah, it’s painful), but when she works, she works. That 80-cost Elemental Burst is demanding, but the multiplicative scaling payoff is chef’s kiss.
Rarity and Accessibility—The Real Talk
Xianyun requires limited banner pulls, but she’s fantastic right out of the box at C0. Her signature weapon Crane’s Echoing Call is optimal, though Favonius Codex and Thrilling Tales work just fine if you’re budget-conscious.
Faruzan’s the classic 4-star trap. Sure, she’s easier to pull, but her true potential is locked behind C6. Pre-C6, those energy constraints (275-300% ER) often create more headaches than the damage benefits are worth.
DPS Contribution Analysis: The Numbers Game
Damage Amplification Mechanics
With 4,500 ATK, Xianyun’s C0 provides 9,000 flat damage before multipliers. Factor in Xiao’s typical 70% CRIT Rate and 200% CRIT DMG? That’s 15,300 average damage increase per plunge. Her C2 doubles this to 18,000 flat damage—absolutely ridiculous.
Faruzan’s approach is different but equally impressive. That 30% Anemo RES Shred translates to 15-30% damage increase against most enemies, while her 32.4% Anemo DMG Bonus provides direct multiplicative scaling. At C6, the additional 40% Anemo CRIT DMG can push Xiao’s plunging attacks beyond 100,000 damage per hit. Yeah, you read that right.
Buff Duration and Uptime
Xianyun’s got excellent uptime—16-second Elemental Burst with only an 18-second cooldown means just 2 seconds of downtime. Her Adeptal Assistance stacks give you 8 buffed plunging attacks per rotation, which aligns perfectly with Xiao’s Burst duration.
Faruzan’s base setup is… less forgiving. Twelve seconds of buff duration with a 20-second cooldown creates those annoying 8-second gaps. Her C2 extends this to 18 seconds, which significantly improves things, but that’s another constellation investment.
Xianyun Support Breakdown: The Adeptal Healer
Plunge Attack Buffs and Mechanics
Xianyun’s plunge buff activates through her A4 Passive after using Elemental Burst, granting 8 stacks of Adeptal Assistance. Each stack enables one enhanced plunging attack with that juicy flat damage bonus. To hit the damage cap, you’ll want Xianyun at 4,500 ATK.
Here’s the beautiful part—that flat damage bonus applies before all multipliers. So a well-built Xiao with 200% CRIT DMG effectively triples Xianyun’s base damage contribution through critical hits. It’s multiplicative scaling disguised as additive damage.
Healing Integration That Actually Works
Xianyun’s healing follows the active character throughout her 16-second Burst duration. This perfectly counters Xiao’s HP drain while keeping everyone alive, and it enables those powerful Furina synergies where HP fluctuations generate Fanfare stacks for massive DMG% buffs.
Her A1 Passive throws in additional CRIT Rate buffs (4-10% depending on enemies hit) for 20 seconds. Not game-changing, but every bit helps.
Build Requirements—Keep It Simple
Xianyun needs Energy Recharge until requirements are met (120-130% with C6 Faruzan, 200-210% without), then it’s all about stacking ATK% to reach that 4,500 cap. Main stats: ER%/ATK% Sands, ATK% Goblet, ATK%/Healing Bonus% Circlet.
Her signature weapon Crane’s Echoing Call is optimal with high Base ATK, ATK% substat, team-wide Plunging Attack DMG buff (28%), and energy restoration. Favonius Codex works great for energy support, and Thrilling Tales provides massive ATK% transfer to Xiao.
Faruzan Support Analysis: The Anemo Specialist
Anemo RES Shred—Why It Matters
Faruzan’s 30% Anemo RES Shred provides roughly 22% damage increase against standard 10% Anemo resistance enemies. Her 32.4% Anemo DMG Bonus stacks multiplicatively with other DMG% sources, which is where things get spicy.
The resistance shred applies through her Elemental Burst’s Pressurized Collapse effect. Positioning matters here—enemies need to be within the burst area for maximum effectiveness.
Constellation Scaling—The C6 Transformation
This is where Faruzan goes from decent support with energy issues to absolute unit. Her C6 provides 40% Anemo CRIT DMG bonus and triggers Pressurized Collapse vortexes every 3 seconds, solving those energy generation problems while maximizing damage output.
Managing team resources for constellation investments requires careful planning. Team rebuild recharge budget considerations become essential when targeting specific constellations, and BitTopup’s flexible payment options and bonus crystal packages help optimize your investment efficiency while maintaining account security.
Pre-C6 Faruzan needs 250-300% Energy Recharge, making her extremely difficult to build effectively. Her C2 extends burst duration from 12 to 18 seconds, significantly improving rotation flexibility.
Energy Management Reality Check
Faruzan’s 80-cost Elemental Burst creates substantial energy demands. C0 requires 275-300% ER, C1-C5 needs 235-260%, while C6 drastically reduces requirements through improved particle generation.
Favonius Warbow is practically mandatory for most constellation levels, reducing ER requirements by approximately 35% with its 61.3% ER substat and particle generation passive.
Head-to-Head DPS Calculations
The Math That Matters
Xianyun’s C0 adds 9,000 flat damage per plunge before multipliers. With typical CRIT stats, this becomes 15,300 average damage increase per plunge. Straightforward and reliable.
Faruzan’s multiplicative buffs scale with Xiao’s base damage. Against a baseline 50,000 damage plunge, her 30% RES shred and 32.4% DMG bonus combine for roughly 70% total increase, pushing damage to 85,000+ per plunge. Her C6 adds another 40% CRIT DMG, easily pushing totals beyond 100,000.
But here’s where it gets interesting—combined usage creates multiplicative scaling where Xianyun’s flat damage gets amplified by Faruzan’s percentage-based buffs. A 59,000 base plunge (50,000 + 9,000) becomes 100,300+ with Faruzan’s full buffs.
Investment Return Analysis
C0 Xianyun provides immediate, substantial returns with minimal building requirements beyond ER thresholds. Faruzan’s investment curve shows that dramatic improvement at C6, transforming from challenging support to top-tier enabler.
Cost-effectiveness? C0 Xianyun + C6 Faruzan seems to be the sweet spot for maximum DPS ceiling with reasonable resource allocation.
Team Composition Strategies
The Dream Team Setup
The highest-rated composition combines both supports: Xiao, Xianyun, Faruzan, Furina (SS-Tier). This maximizes synergies where Xianyun’s healing enables Furina’s Fanfare stacks, Faruzan amplifies Anemo damage, and all buffs stack multiplicatively. It’s beautiful when it works.
Alternative approach replaces Furina with Bennett: Xiao, Xianyun, Faruzan, Bennett. More straightforward damage amplification without the HP management requirements.
Rotation Execution—Timing Is Everything
Optimal rotation sequence: Faruzan Burst (and Skill if C2+), Furina Skill then Burst, Xianyun Skill with enhanced plunge then Burst, finally Xiao double Skill then Burst with plunging attacks.
This ensures all buffs are active before Xiao takes field time. You’re working with Faruzan’s 12-second base duration (18 with C2), Xianyun’s 16-second duration, and Xiao’s 15-second Burst window.
Constellation Investment Guide
C0 Performance Baseline
C0 Xianyun functions as a complete support with 9,000 flat damage per plunge and reliable healing. Energy requirements remain manageable (200-210% ER with non-C6 Faruzan).
C0 Faruzan provides core Anemo buffs but suffers from severe energy constraints requiring 275-300% ER. The building requirements often outweigh benefits for casual players.
Key Constellation Breakpoints
Xianyun’s C2 doubles her flat damage contribution from 9,000 to 18,000 per plunge, plus provides 20% ATK increase for 15 seconds after Skill usage. Solid upgrade, but not game-changing.
Faruzan’s C6? That’s the game-changer. The 40% Anemo CRIT DMG bonus and improved energy generation solve core functionality issues while maximizing damage output.
Investment Priority—Where to Spend Your Primos
For maximum DPS impact, prioritize C6 Faruzan over Xianyun constellations. The C6 transformation provides larger DPS gains than any Xianyun constellation upgrade.
Budget-conscious players should focus on C0 Xianyun for immediate improvement, then save for C6 Faruzan during favorable banners. Whale players benefit from C2 Xianyun + C6 Faruzan combination for absolute highest DPS ceiling.
Practical Application: Spiral Abyss Performance
Floor-Specific Advantages
High HP enemy floors favor the combined support approach for sustained DPS through extended rotations. Burst damage windows slightly favor Faruzan’s multiplicative scaling, particularly at C6. Environmental damage floors strongly favor Xianyun inclusion for team sustainability.
Enemy Type Considerations
High Anemo resistance enemies benefit more from Faruzan’s 30% RES shred. Mobile enemies favor Xianyun’s healing-following mechanics over Faruzan’s area-dependent effects. Multiple enemy scenarios benefit from Xianyun’s team-wide healing and Furina synergy.
Clear Time Reality Check
Optimal teams using both supports consistently achieve faster clear times than single-support alternatives. C6 Faruzan teams show 20-30% clear time reduction over pre-C6 versions. Xianyun-enabled Furina teams demonstrate superior performance in sustained encounters through Fanfare stacks and healing utility.
Final Verdict: Your Xiao Support Strategy
Situation-Based Recommendations
Need immediate improvement with minimal investment? Go with C0 Xianyun. Her complete functionality, healing utility, and team enablement provide excellent value right out of the gate.
Want maximum DPS ceiling regardless of cost? Pursue both supports with priority on C6 Faruzan. The combined approach delivers the highest possible damage output.
Working with F2P/limited resources? C0 Xianyun offers better immediate returns than pre-C6 Faruzan, whose energy requirements create more problems than benefits.
Long-term Meta Considerations
Xianyun’s versatility extends beyond Xiao teams—she supports plunge-based compositions for multiple DPS characters including Diluc, Gaming, and future releases. Faruzan’s specialization in Anemo support makes her essential for Anemo hypercarry teams but limits utility in diverse compositions.
The ultimate answer isn’t choosing between Xianyun and Faruzan. It’s understanding how they work together to create Xiao’s strongest possible team composition while matching your investment level and playstyle preferences.
