Should You Pull?SITUATIONAL

Situational—Rebecca is an Electro all-DMG / Heavy Attack amp hybrid. Liberation “Party 'til Dawn!” applies shield or damage reduction for the active Resonator. Best with Xiangli Yao / Yinlin / Shorekeeper. Heavy Attack amp is wasted on Skill/Liberation-only Electro carries. Skip when Electro amp seats are already full.

Rebecca is a 5★ Electro Main DPS who fights with a Pistols. Liberation “Party 'til Dawn!” applies shield or damage reduction for the active Resonator. Forte “Gloves Are Comin' Off!” dumps a large Liberation multiplier into the current wave.

Strengths

  • Liberation “Party 'til Dawn!” applies shield or damage reduction for the active Resonator — that window is where Rebecca’s clear speed actually shows up.
  • Forte “Gloves Are Comin' Off!” dumps a large Liberation multiplier into the current wave, so resource banking is mandatory, not optional filler.
  • Outro “Preem Choom” hands the next Resonator a Heavy/Basic Attack Amplification window — swap timing is part of the damage plan, not just Concerto filling.
  • Aerial / plunge routes give flexible dodge and reposition options mid-combo.

Weaknesses

  • Field-time hungry once Liberation “Party 'til Dawn!” is up — double-DPS swaps dilute the dump window.
  • Wants dedicated supports and ER planning; dropped into a random squad, Liberation uptime falls off a cliff.
