SCROOMS instrument cards use six printed fields: Precision, Harmony, Tension, Luck, Tune Speed, and Resonance. Read them as a troubleshooting set. First identify the catch stage that fails, then compare the stat linked to that job. Do not add the numbers together into an unsupported “power score.”
The official description explicitly connects Tune Speed with faster tuning. The other practical meanings below are community reported from current guides and tooltips; the live Equipment Bag card is the best source for your version.
Stat-by-stat diagnosis
Precision
Use it when comparing how demanding the opening timing or alignment feels. Higher printed Precision is commonly treated as more forgiveness, but test the current card rather than assuming a formula.
Harmony
A general catch-performance field on instrument cards. Public sources do not provide a reliable standalone formula, so compare it only alongside a repeatable encounter.
Tension
Current guides associate it with how closely the Scroom follows your marker in the catch zone. Use it when the target repeatedly slips out after tuning succeeds.
Luck
A rare-attraction or rarity-oriented field in community explanations. It is not a displayed probability for a named species.
Tune Speed
The official description says a faster value makes the tuning stage quicker. Negative Tune Speed on a card is therefore a meaningful tradeoff.
Resonance
Use it to match instrument reach to the Index frequency band. A tool can feel comfortable but still fail if it cannot reach the target Hz.
Opening Grove card comparison
The Wooden Lute is the free baseline: reported +2% Precision, zero Harmony, zero Tension, zero Luck, and Resonance I. The Tamer’s Guitar is the 100-Chime tutorial step, commonly reported at +6% Precision, +5 Harmony, +20 Tension, and +5% Luck.
The 750-Chime Adventurer’s Tambourine is commonly reported at +5% Precision, +8 Harmony, +30 Tension, +8% Luck, +15% Tune Speed, and Resonance II. The 4,500-Chime Violin of Pilgrimage is commonly reported at +4% Precision, +10 Harmony, +30 Tension, +40% Luck, +5% Tune Speed, and Resonance II.
Those lines produce different choices. Guitar has the highest reported Precision of the four, Tambourine has the highest Tune Speed, and Violin has the highest Luck and Harmony. Price does not make one card lead every field.
Match the symptom to a stat
You cannot move the tuner far enough. Read the target’s Index band and compare Resonance. This is a reach problem, not a Luck problem.
You can reach the band but settling takes too long. Compare Tune Speed. The official description directly supports this relationship.
You finish tuning but lose progress in the moving zone. Practice tracking first, then compare Tension and any live tooltip explaining control behavior.
The opening timing input is inconsistent. Practice on a common target and compare Precision. Do not expect Luck to fix timing.
You want rare variants. Compare Luck only after reach and control are sufficient. A high printed value does not guarantee the next spawn.
Later cards and tradeoffs
Current community tables report Resonance IV on Prospector’s Lute and Blackwood Fiddle, and Resonance V on Deepchord. This makes them relevant to later high-frequency bands. Deepchord is also reported with very high Tension, while its acquisition requires a quest route and a 16,000-Chime purchase in current guides.
Lotus Hymn is reported with +25% Tune Speed, while Stillwater Flute is reported with a very high Luck line and negative Tune Speed. That is a clear example of why “later” or “more expensive” does not mean universally faster. Verify both cards in your server because those values currently rely on community reporting.
Run a clean comparison
- Pick one species whose frequency your old and new instruments both reach.
- Record the card values and confirm the new tool is equipped.
- Perform several catches with the old tool, noting tuning time and where failures occur.
- Repeat with the new tool in the same area and control setup.
- Separate timing misses, frequency misses, and catch-zone escapes.
- Keep the result as a handling comparison, not a universal hidden-stat formula.
Avoid comparing a Common Redcap with a later Fabled target and attributing every difference to the instrument. The species, band, movement, rarity, and your familiarity changed at the same time.
Read percentages carefully
A printed +40% Luck is an equipment modifier, not a claim that a particular Fabled has a 40% spawn chance. A +15% Tune Speed line indicates a relative stat bonus, not an exact number of seconds saved for every encounter. A Roman-numeral Resonance tier is a category, not a frequency value in Hz.
If you want to share a result, include the date, instrument card, target species, area, and number of attempts. Do not label a small personal sample official. The frequency guide keeps Hz bands separate from rarity and odds.
FAQ
Which stat increases frequency reach?
Resonance is the field associated with reachable frequency bands in current guides. Compare it with the target Index card.
Which stat makes tuning faster?
Tune Speed. This link is stated in the official SCROOMS description.
Does Luck increase catch success?
Current guides describe Luck as affecting rare attraction or rarity outcomes, not as a substitute for timing, reach, or catch-zone control. No supported public formula gives a named-species chance.
Why does a costly instrument have lower Precision?
Cards trade between fields. The Violin’s commonly reported strength is Luck and Harmony, while the cheaper Guitar has a higher printed Precision line. Choose for your objective.
