Conductive Silent Zone" Echo Comparison and Recommendations (Rubble Highlands, Concord Mountains)
Currently, there are 2 Tacet Field areas: in the Rubble Highlands Tacet Field, you can find Conduction and Fusion Echoes, and in the Harmony Mountains Tacet Field, you can find Conduction and Glacial Echoes.
If you're farming Conduction-type Tacet Fields for the 1.4 second-half rerun Resonators and Lumi, we recommend the Rubble Highlands Tacet Field!
📌Rubble Highlands is better for Conduction-type Echo Tacet Fields
· The Echo drop rate is the same in all Tacet Fields
· There are overlapping Conduction/Fusion and Conduction/Glacial Echoes, so the total number of Echoes differs in each area.
·To acquire more Conduction-type Echoes, we recommend the Rubble Highlands, which has a higher expected value.

✅Calculation of Expected Value of Conduction Echoes by Tacet Field
· The expected value of Conduction Echoes is slightly higher in the Rubble Highlands Tacet Field.
| Item | Rubble Highlands | Harmony Mountains |
|---|---|---|
| Echo Type | Conduction (8), Fusion (7), Conduction+Fusion (6) | Conduction (13), Glacial (13), Conduction+Glacial (1) |
| Total Number of Echoes | 21 | 27 |
| Probability of Acquiring Conduction Attribute | (8/21) + (6/21) × (1/2) = 11/21 | (13/27) + (1/27) × (1/2) = 13.25/27 |
| Number of Echo Drops (60 Plate) | 4 | 4 |
| Expected Value of Conduction Echoes | 4 × (11/21) ≈2.10 | 4 × (13.25/27) ≈1.96 |
✅Rubble Highlands: Conduction + Fusion Echo
· Total of 14 types of Conduction Echoes / Total of 13 types of Fusion Echoes
·Conduction + Fusion Echo: 5 x 1-Cost Echoes / 1 x 3-Cost Echo
· When acquired in the Rubble Highlands Tacet Field, you acquire 1 attribute of either Conduction or Fusion

✅Harmony Mountains: Conduction + Glacial Echo Types
· Total of 14 types of Conduction Echoes / Total of 14 types of Glacial Echoes
·Conduction + Glacial Echo: 1 x 3-Cost Echo
· When acquired in the Harmony Mountains Tacet Field, you acquire 1 attribute of either Conduction or Glacial
