Aemeath is a 5-star Fusion Sword wielder who functions as a main DPS character in Wuthering Waves. Her kit revolves around two distinct Resonance Modes—Tune Rupture for single-target damage and Fusion Burst for area-of-effect scenarios—and her damage output scales heavily with Resonance Liberation abilities. Like most limited 5-star characters, her true potential unlocks through Resonance Chains, which are character-specific upgrade nodes that fundamentally reshape how she plays.
Quick answer: Resonance Chain 3 (RC3) offers the best balance of power and flexibility for most players, doubling your ultimate's damage and removing team restrictions. If you can only afford one, RC1 provides immediate combat flow improvements and a significant damage spike.
RC1: Gilded Glimmer of the First Dawn
This chain delivers three distinct benefits that work together to improve your rotation. Your Heavy Attacks gain a 300% critical damage boost while in Instant Response, substantially amplifying burst windows. More importantly, it introduces a target-switching mechanic that records the highest stack count of Rupturous or Fusion Trail when you defeat an enemy, then applies those stacks to your next target. This solves a core problem in multi-wave combat where damage amplification buffs vanish when enemies die.
The chain also lets you enter Instant Response outside of combat after 4 seconds of inactivity, which improves exploration feel and makes continuous battles smoother. For a main DPS character, this combination of damage, mechanical utility, and quality-of-life improvements makes RC1 feel complete right away.
RC2: Downy Notes of Snowfluff
This upgrade doubles the damage multiplier of your core skill, Duet of Seraphic Plumes—both the Overture and Encore versions. It's a straightforward damage leap that applies in both Resonance Modes. In Fusion Burst mode, defeating enemies also triggers an immediate explosion based on current Fusion Burst stacks, enhancing crowd-clearing capability.
While the damage boost is significant, RC2 feels incremental compared to RC1 and RC3. It solidifies your core skill output but doesn't unlock new mechanics or remove constraints.
RC3: Fervor Sightly Burns Bright as New
RC3 is the game-changing upgrade that unlocks Aemeath's full independence. It doubles the damage multiplier of your ultimate, Heavenfall Edict—Finale, delivering the single largest damage increase to your finisher. More importantly, it removes team restrictions from your Inherent Skill "Between the Stars," allowing you to self-activate the full 60% critical damage and 20% defense-ignore buff without needing specific teammates.
This self-sufficiency is the real value. You're no longer locked into running characters who trigger Tune Rupture or Fusion Burst effects just to maximize your personal buffs. You can build flexible team compositions around whatever supports your playstyle. Combined with the ultimate damage doubling, RC3 represents a fundamental unlock in both power and team-building freedom.
RC4: Ethereal Waltz on Binary Tides
This chain transforms Aemeath into a team amplifier. Whenever you use your Intro Skill or core Resonance Skills, all teammates gain 20% all-attribute damage bonus for 30 seconds. In coordinated, end-game team scenarios, this significantly boosts overall party DPS beyond your own numbers.
RC4 is a luxury investment. It's valuable if you're optimizing for maximum team output, but it doesn't improve Aemeath's personal damage or unlock new playstyle options.
RC5: Voyage to the Astral Shore
This chain focuses on exploration and survivability. Defeating enemies resets your Mech form's flight stamina, greatly improving traversal efficiency in the open world. You also gain a one-time revival mechanic that triggers when you take fatal damage, entering a "2D Digital Ghost" state that shields your team for 5 seconds before reviving you with full health. This effect has a 10-minute cooldown, making it a reliable but occasional safeguard rather than a core combat tool.
RC5 is purely convenience-focused and doesn't impact combat performance.
RC6: A Zephyr-Kissed Journey to You
RC6 represents Aemeath's absolute power ceiling. Enemies take 40% increased Resonance Liberation damage from you universally. Your Tune Rupture and Fusion Burst damage can now critically hit with fixed stats—80% critical rate and 275% critical damage—removing reliance on crit scaling. The chain also doubles the stack application and maximum limit of your core Rupturous and Fusion Trail effects, supercharging your fundamental mechanics.
RC6 unlocks multiplicative damage scaling that far exceeds lower investment levels. It's the ultimate power spike for players committed to maximizing Aemeath's ceiling.
Choosing your investment path
For most players, RC3 is the optimal stopping point. It delivers two colossal damage multipliers for your most important skills and, critically, removes team dependency. That self-sufficiency unlock is often more valuable than raw numbers alone because it lets you experiment with team compositions and playstyles without sacrificing your personal buffs.
If your resources are extremely limited, RC1 is the most impactful single investment. The critical damage boost, target-switching mechanic, and out-of-combat utility make your rotations feel complete and powerful immediately.
The natural progression for maximum potential is RC1 → RC2 → RC3. RC2 solidifies your core skill damage, and RC3 unlocks your ultimate's full power plus complete playstyle independence. Beyond RC3, RC4, RC5, and RC6 are luxury investments for players seeking to maximize team synergy or reach absolute damage ceilings.
Signature weapon versus RC1
Aemeath's signature weapon, Everbright Polestar, provides 12% all-attribute damage bonus and makes your Resonance Liberation damage ignore 32% defense and 10% Fusion resistance for 8 seconds when you apply Tune Rupture or Fusion Burst effects. That defense-ignore effect is one of the rarest damage multipliers in the game.
RC1 offers more than pure damage. It provides essential combat flow through the target-switching mechanic and exploration benefits that the weapon doesn't touch. For a main DPS character, RC1's comprehensive upgrade is typically slightly preferred if you must choose between the two.
The most powerful early setup combines RC1 with the signature weapon. RC1 ensures smooth, powerful rotations, while the weapon's defense-ignore dramatically amplifies the damage of those rotations. If resources are tight, prioritize RC1 first, then consider the weapon afterward.
Pair your chosen Resonance Chain investment with the Trailblazing Star Echo set for 20% critical rate and 20% Fusion damage bonus, and you'll have a stellar main DPS ready for Version 3.1 content and beyond.
