WHERE & HOW TO FARM
Where to farm
Heart of Stillness Tacet Field in the Simulacrum Nexus.
Heart of Stillness is one of the Nexus Tacet Fields. Clear its encounter and claim the Waveplate reward for the field’s displayed Echo materials and set opportunities. A field is a repeatable resource activity, but its value depends on the current reward preview and your build plan. Check the in-game set labels before committing Waveplates, then stop once the target build no longer needs its output.
Unlock the Nexus and the field through region progression.
Have Waveplates for each reward claim.
Know which Echo Sonata sets or Echo upgrade materials your build needs.
Be able to clear the displayed field encounter reliably.
Open the map or activity interface and select Heart of Stillness Tacet Field.
Inspect the live reward preview, including the Echo sets and materials shown for the field.
Compare those sets with the Resonator build you are farming; leave if neither set is useful.
Enter the field and defeat the Tacet Discord groups in the encounter.
Use the reward prompt and spend Waveplates only when the output fits your target.
Review the resulting Echoes and materials in inventory, keeping pieces that serve the build and sorting the rest according to your Echo management plan.
Repeat while the set or field materials remain useful and you have Waveplates to claim.
Farming tips
The Version 3.7 sources confirm new field content, but the client’s reward preview is the appropriate place to confirm the current field pool.
Echo outcomes depend on Data Bank progression; treat each claim as an attempt, not a guaranteed useful piece.
Repeat, collect and use
Repeatable while you have Waveplates. The field encounter can be cleared again, but reward claims consume Waveplates.
Common mistakes
Claiming before checking sets: inspect the live preview and choose a field aligned with the build.
Expecting a specific Echo or main stat every time: evaluate the drops you receive and continue only if the target remains worth the cost.
Spending Waveplates when you only need overworld Echo attempts: switch to open-world Tacet Discords for a no-claim route.
When to stop or switch
Stop when you have the usable set pieces or Echo materials needed, or switch fields if its live set pool no longer supports the build.
