Are Transducers worth it for Data Modify?
Usually not. A Transducer costs the Afterglow Coral of 3.75–7.5 limited pulls. Double crit from an echo with no crit takes about 4 Transducers: 15–30 pulls, about $29–$59.
The price
Transducer: 30 Afterglow Coral for the first 2 each version, then 60.
Radiant Tide (1 limited pull): 8 Afterglow Coral.
1 Transducer = 3.75 pulls (first 2 each version), then 7.5 pulls.
1 pull ≈ $1.98 at the $99.99 Lunite pack, so 1 Transducer ≈ $7.42–$15.
With Lunite Subscription Astrite, 1 pull ≈ $0.27, for up to 18 pulls a month.
Afterglow Coral only comes from pulls: 3 per 4★, 15 per 5★ Resonator, and 30 more when the 5★ is off-banner.
No refund: a discarded echo, or a reroll that you do not keep, returns no Transducers.
Farming vs Transducers, double crit
| Route | Echoes | Tuners | Premium Tubes | Pulls of Coral |
|---|---|---|---|---|
| Max every echo | 7.8 | 288 | 77.2 | 0 |
| One echo + Data Modify | 1 | 50 | 28.6 | 15–30 |
Echoes, Tuners, and tubes come back from farming. Pulls do not.
Data Modify saves about 6.8 echoes, 238 Tuners, and 48.6 Premium Tubes: 1.7 echoes per Transducer.
Farming it: about 16 Tacet Field runs, 4 days of Waveplates, or $12 in refills. Echo drops not counted.
Data Modify: $29–$59 in pulls.
The best case: keep a rare roll
A lock keeps the value too. So the best echo is one that already rolled a rare value.
Example: Crit. DMG ≥ 21.0% on the echo (a 3.00% roll), Crit. Rate missing.
| Route | Echoes | Tuners | Premium Tubes | Pulls of Coral |
|---|---|---|---|---|
| Max every echo | 260 | 9,115 | 1,880 | 0 |
| One echo + Data Modify | 1 | 50 | 28.6 | 11–23 |
Data Modify saves about 259 echoes: 86.3 echoes per Transducer, against 1.7 for plain double crit.
Farming it: about 456 Tacet Field runs, 114 days of Waveplates, or $338 in refills. Echo drops not counted.
Data Modify: $22–$45 in pulls.
Locks
Best: 1 or 2 locks, with 1 goal stat missing.
Worst: 3 or 4 locks. Each reroll costs more, and fewer slots reroll.
| Goal stats locked | Chance per reroll | Per reroll | Expected | Pulls of Coral |
|---|---|---|---|---|
| 1 | 33.33% | 1 | 3 | 11–23 pulls |
| 2 | 27.27% | 1 | 3.7 | 14–28 pulls |
| 3 | 20.00% | 2 | 10 | 38–75 pulls |
| 4 | 11.11% | 3 | 27 | 101–203 pulls |
Values reroll too. With 1 lock and Crit. DMG ≥ 16.2% as the missing stat: 10.00% per reroll, 10 Transducers, 37–75 pulls.
Lock only goal stats. With Crit. Rate kept, the chance for Crit. DMG is 33.33%. Lock ATK% too, and it falls to 27.27%.
Who should use them
Most players: skip them, and spend Afterglow Coral on pulls.
Endgame players: the 2 cheap Transducers each version, on an echo with a rare roll to keep that needs 1 more stat.
The 60-Coral price: only when farming time is worth more to you than pulls.
Never to chase a top roll on a stat that rerolls. Top rolls are rare, and each reroll rolls the values again.
This is what the numbers show. Every account needs different things, so weigh it against your own.
