Wuthering Waves · 5★ Resonator
"Fury-Type Arsenal" The Edgerunner crew's fiery gunslinger
Rebecca is the second Edgerunner to arrive through the Cyberpunk: Edgerunners collaboration and Lucy's crewmate, a restless gunslinger who is always ready to blow her problems away with her shotgun. She wields Pistols with the Electro element. She switches between Huntress and Guts modes with her Resonance Skill and Intro, and once Fervor is full, she performs powerful Heavy Attacks that pull enemies in and riddle them with bullets. In her Liberation, she switches to the Mk. 31 HMG heavy machine gun and floods the area with fire. In the team she is a sub DPS: Her Outro gives the next character 15% All DMG Amplification and up to 35% Heavy Attack DMG Amplification, and she shares the Hack - Shifting mechanic with Lucy.
Rebecca was the free character of the Cyberpunk: Edgerunners collaboration: Throughout version 3.4, anyone who reached Union Level 10 and logged in for 10 days during the "Instant Flashlight" event could claim her until July 9, 2026. For her Sequences there was the "Rekindled Embers of Rage" banner, which ran from June 8 to July 9, 2026; this banner used the collaboration-exclusive Dreamcatcher Tide, and its pity was shared with Lucy's banner. As of version 3.6, neither the event nor the banner has returned.
1-piece: Inflicting Hack - Shifting on the target grants {1} Basic Attack DMG Bonus and Heavy Attack DMG Bonus for {2}s.
Adam Smasher in the main slot activates this set on its own; her Intros and powerful Heavy Attacks apply Hack - Shifting, so the 35% Basic Attack DMG bonus is active on Rebecca very often.
2-piece: Electro DMG + 10%.
Two of the remaining four Echoes give you 10% Electro DMG.
2-piece: ATK + {0}
The last two Echoes are for 10% ATK; 2-piece Lingering Tunes gives the same bonus. This 1+2+2 setup is Rebecca's strongest build.
2-piece: Energy Regen + {0}.
5-piece: Upon using Outro Skill, increases the ATK of the next Resonator by 22.5% for 15s.
If you play Rebecca as a pure support, use 5-piece Moonlit Clouds with Impermanence Heron as the main Echo; it gives the next character 22.5% ATK after the Outro.
Reminiscence - Nightmare: Adam Smasher
In the main slot it gives Rebecca 15% Crit. Rate and turns her Echo Skill into a barrage of 16 Electro missiles, each hitting for 17.1% of ATK.
Use the 4-3-3-1-1 layout; bring Energy Regen to around 125% so you can use the Liberation every rotation, then stack crit stats.
Signature weapon. On top of a 72% Crit. DMG main stat and 12% ATK, it grants 24% Basic Attack DMG Bonus after the Intro and 12% with Hack - Shifting; Hack - Shifting also increases the whole team's ATK by 24% for 30 s.
The standard banner's 5★ Pistols; grants a 48.6% Crit. DMG main stat, 12% ATK and 20% All-Attribute DMG Bonus when a teammate performs a Tune Break.
24.3% Crit. Rate main stat; the 36% Basic Attack DMG Bonus after Intro or Basic Attack damage matches Rebecca's damage type perfectly.
The standard banner's 5★ Pistols; its Energy Regen passive covers her energy needs, and it gives the next character 10% ATK after the Outro. Good for support-focused play.
The most sensible 4★ option: A Crit. Rate main stat and an ATK bonus that stacks with Basic or Heavy Attack hits.

Rebecca fights in two modes: In Huntress, she has a 3-hit Basic Attack and a Heavy Attack that consumes STA to fire continuously and counts as Basic Attack damage; in Guts, a 3-hit shotgun combo and a single-shot Heavy Attack. In both modes, pressing Dodge mid-attack triggers Tactical Dodge, which fires while evading; a successful dodge deals extra Electro damage.
In Huntress mode, It's Big Boomin' Time! closes in on the target, rains bullets on it and switches to Guts to blast it with the shotgun; in Guts mode, Come 'n' Get Me! uses the recoil to dash away and returns to Huntress. Each use switches modes, and its hits fill Fervor.
Huntress mode increases Crit. DMG by 30%, and Guts mode ignores 15% of the target's DEF. Attacks fill up to 120 Fervor; when it is full, the Heavy Attack turns into Rat-tat-tat! or Bang-bang-bang!, which pull enemies in, deal Basic Attack damage and apply Hack - Shifting. If you use the Intro or Resonance Skill while the self-filling Hot Hand is at 120, A Girl Gets What She Wants! activates and grants the bonuses of both modes at once for 12 s.
Switches to the Mk. 31 HMG and sets up a 9.5-second Stagnation field; the automatic fire counts as Basic Attack damage, and you can raise the firepower twice by pressing Normal Attack or Liberation. During this time Rebecca cannot move but gains 50% damage reduction and interruption immunity; when the mode ends or Overload fills to 90, the BOOM! Fireworks! blast follows, which also applies Hack - Shifting.
She has two different entries depending on her mode: In Huntress she closes in, rains bullets and switches to Guts; in Guts she dashes back with the recoil and returns to Huntress. Both Intros apply Hack - Shifting; if Hot Hand is full, they start A Girl Gets What She Wants! and grant 50 Fervor.
Sets up a turret that fires at enemies for 14 s. Through Edgerunner Bonds, the next character gains 15% All DMG Amplification for 14 s and, thanks to Overlimit stacking every 0.2 s, up to 35% Heavy Attack DMG Amplification; Lucy receives all of these stacks instantly and can make the turret short-lived but much stronger.
When A Girl Gets What She Wants! triggers or Rat-tat-tat!/Bang-bang-bang! is used, she gains 10% ATK for 12 s (stacks 2 times). When a teammate applies Hack - Shifting, that character's Tune Break Boost increases by 30 for 30 s.
Rat-tat-tat! and Bang-bang-bang! become more resistant to interruption. When the Resonance Liberation is used, the ATK of all nearby teammates increases by 20% for 30 s; a large part of Rebecca's support value comes from this passive.
She can perform a Tune Break on a target whose Off-Tune level is full. When a teammate's Tune Break triggers Hack - Interfered, Rebecca responds with Meltdown, an Electro explosion that counts as Hack damage, on the affected targets in range (once every 8 s per target).
Her free S0 version handles her job in the team comfortably. If you pull for copies, the most valuable stop is S2, because it gives the whole team 20% All-Attribute DMG Bonus and 15% All DMG Amplification with Hack - Shifting; S6 significantly increases her personal damage.
The multipliers of Basic Attack, Heavy Attack, Tactical Dodge and Dodge Counter in Huntress and Guts modes increase by 50%; A Girl Gets What She Wants! grants 3 Street Smarts stacks, and Tactical Dodge restores 20 STA per stack. BOOM! Fireworks! becomes immune to interruption.
After an Intro or Liberation, the whole team gains 20% All-Attribute DMG Bonus for 30 s; teammates who apply Hack - Shifting also gain 15% All DMG Amplification for 30 s.
The multipliers of Party 'til Dawn! and BOOM! Fireworks! increase by 60% and the blast area expands by 30%; Intros instantly grant 120 Hot Hand.
The mode bonuses she gets from A Girl Gets What She Wants! become 60% stronger.
Applying Hack - Shifting grants 20% Basic Attack DMG Bonus for 8 s.
Basic Attack DMG Bonus from all sources increases by 40%; during Rat-tat-tat!/Bang-bang-bang!, she lands an extra hit for 900% of ATK. She does not go down from a fatal blow and restores a flat 2077 HP 5 times (once every 10 minutes); after more than 4 s out of combat, she gains 120 Fervor.
Hack - Shifting is unique to this duo: Rebecca's Outro instantly gives Lucy 35% Heavy Attack DMG Amplification, and Lucy's Outro boosts Rebecca's Basic Attack damage. Mornye completes the team with 25% All DMG Amplification.
Yangyang (Xuanling)
Rebecca
Chisa
Rebecca's Heavy Attack buff is tailor-made for the big hits of Yangyang: Xuanling; Chisa raises the targets' Havoc Bane stack cap, feeding her passives.
Jingran
Rebecca
Shorekeeper
Like any main DPS that relies on Heavy Attacks, Jingran gets a big boost from Rebecca's Outro; Shorekeeper provides healing and a crit bonus.

Rebecca was given out for free during the Cyberpunk: Edgerunners collaboration (version 3.4): Reaching Union Level 10 and logging in for 10 days during the "Instant Flashlight" event was enough. The "Rekindled Embers of Rage" banner opened for her Sequences; the event and the banner ended on July 9, 2026 and had not returned as of 3.6.
Use Reminiscence - Nightmare: Adam Smasher in the main slot for 1-piece Shadow of Shattered Dreams, alongside 2-piece Void Thunder and 2-piece Reel of Spliced Memories (or Lingering Tunes). If you want to play her as a pure support, 5-piece Moonlit Clouds with Impermanence Heron is also an option.
Her signature weapon Skull Thrasher is the best: Besides a 72% Crit. DMG main stat, it gives the team 24% ATK. Alternatives include the standard Phasic Homogenizer and Static Mist, Spectrum Blaster or the 4★ Solar Flame.
Even her free S0 version is a strong sub DPS in Heavy Attack teams and does her job. If you pull for copies, S2, which gives the team a big buff, is the most sensible stop; S6 is mostly for personal damage.
The best team is Lucy + Rebecca + Mornye; Hack - Shifting is unique to this duo. Her Outro boosts Heavy Attack damage, so she also works very well with Heavy Attack DPS units such as Yangyang: Xuanling and Jingran.
For Ascension she needs Nightmare Flashdrive from Nightmare: Adam Smasher, Past Reveries and Mech Cores. Her skills use the Combustor series, Mech Cores and We Who Question from the weekly boss Denia.
