❓ FAQ — Heartstring Nocturne

Is Heartstring Nocturne worth pulling?
Heartstring Nocturne is a Limited S-Rank Attack W-Engine with 713 Base ATK and CRIT Rate 24%. It's a strong upgrade for Attack agents who need CRIT Rate. If you main a Attack carry, it's worth considering — but an R5 A-Rank alternative can come close in performance for much less Polychrome.
Should I refine Heartstring Nocturne?
Refining a Limited S-Rank is a luxury, not a necessity. Two agents with R1 S-ranks > one agent with R2. Only refine if you have no other Attack agent who needs a strong weapon.
Best F2P alternative to Heartstring Nocturne?
The A-Rank Cannon Rotor and Drill Rig - Red Axis are excellent free alternatives. CRIT Rate 20% provides solid Attack synergy without spending Polychrome. The Battle Pass Cannon Rotor is also a top-tier option for $10.
Does the passive work on off-type agents?
No. The Melody of the Heart only activates when equipped by a Attack agent. Equipping this on any other Specialty gives only raw ATK + CRIT Rate — the passive is completely disabled. Always match W-Engine type to agent Specialty.
