Twin Core efficiency by fishing weight
Twin Cores cost 40 per Twinborn fusion and come only from the fishing event’s cumulative-weight exchange. Each milestone unlocks a normal and a premium exchange.
Cores per 1,000 kg vary by band: the early 500–1,500 kg range is weak, while 10,000–25,000 kg is best. Push weight fast and stay in the high-efficiency range.
