Rebecca Build Guide - Version 3.4
Free 5-star Electro Pistol from the Cyberpunk: Edgerunners collab. Best echo setup, weapon choices, skill priority, and team rotations for Sub-DPS and carry use.
Core Playstyle
Rebecca's damage is front-loaded in her Resonance Liberation: Heavy Machine Gun stance stacks Overload for burst finishers. Build around Electro DMG, ult uptime, and Heavy Attack amp. She is low-investment friendly as Sub-DPS and pairs strongly with Lucy.
1 Skill Priority
Level These in Order
Why Liberation first: Her ult is the main damage source. Under-leveled Liberation means weak Overload stacks and missing the burst finisher damage entirely.
2 Weapon Choice
- Signature (Bonebreaker or equivalent): Best choice for personal buffs and Electro scaling. Pull if you plan heavy use alongside Lucy.
- Strong F2P alternatives: Any 5-star or 4-star pistol with Electro DMG%, ATK%, or Basic/Heavy Attack bonus. She is free, so F2P weapons work well for Sub-DPS role.
- Decision: If on a budget, skip the weapon banner - her base kit as a free unit is strong enough for Sub-DPS without the signature.
3 Echo Setup
Echo Slots (4-3-3-1-1 Cost Format)
| Slot (Cost) | Target Stat |
|---|---|
| 4-cost Main Echo | Electro DMG% or Crit DMG Electro focus |
| 3-cost x2 | Electro Bonus DMG |
| 1-cost x2 | ATK% |
Sonata Sets
- 2pc Electro-focused + 2pc Energy Regen: Core combo for ult uptime and burst damage
- Flexible mixing: 1x one Electro set, 2x another - add Energy Regen pieces as needed for smooth rotation
Substat Priority
- Crit DMG / Crit Rate - maximize burst damage during Liberation
- ATK% - scales all damage
- Energy Regen - ensures ult is available every rotation
- Basic Attack DMG Bonus - secondary scaling in machine gun stance
- Flat ATK - lowest priority, avoid on high-cost slots
4 Best Teams
Core Team (Most Discussed)
Rebecca's outro provides Heavy ATK amp and DMG bonus. Lucy amplifies Basic/Heavy. Strong synergy - Mornye preferred for S1 sustain in extended rotations.
Alternative Teams
5 Rotation Tips
Build concerto/energy carefully - her Liberation finisher gives concerto on hit, not on cast. Extend your opener if needed for early swaps to ensure full concerto generation.
Use stance switches - alternate Hunter/Guts stances for agile pistol play leading into the machine gun ult burst for maximum Overload stacks.
Sub-DPS swap window - swap Rebecca in for burst phase, fire Liberation, amp the team with outro buff, then swap out. Invest more in Lucy if running both - Rebecca unlocks Lucy's full potential.
Common Mistakes to Avoid
Ignoring energy/concerto management - missed ults mean low Overload stacks and her main damage source is gone for that rotation.
Skipping Energy Regen or Crit substats - clunky rotations and weak burst finishers. Both are required for consistent output.
Forcing Main DPS without strong supports - if your account lacks dedicated supports, she performs much more consistently as Sub-DPS.
Farming wrong materials - use community farming infographics for exact material counts before launch to avoid wasted Waveplates.
