❓ FAQ — Yesterday Calls
Is Yesterday Calls worth pulling?
Yesterday Calls is a Limited S-Rank Stun W-Engine with 713 Base ATK and CRIT Rate 24%. It's a strong upgrade for Stun agents who need CRIT Rate. If you main a Stun carry, it's worth considering — but an R5 A-Rank alternative can come close in performance for much less Polychrome.
Should I refine Yesterday Calls?
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 Stun agent who needs a strong weapon.
Best F2P alternative to Yesterday Calls?
The A-Rank Box Cutter and Demara Battery Mark II are excellent free alternatives. Impact 15% provides solid Stun synergy without spending Polychrome.
Does the passive work on off-type agents?
No. The Echoes of the Past only activates when equipped by a Stun 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.
