SCROOMS Mutations Tier List

Mutations and variants multiply the Chimes you earn when you sell a Scroom. This tier list ranks them by sell multiplier, notes how they roll, and flags which ones only appear when a specific instrument is equipped. Stack the right mutation with variants and a Rich dish from the cooking guide before long farm sessions in Crescendo Valley or the Undergarden.

How stacking works

A catch can carry one mutation plus one or more variants. Multipliers multiply together. Example pattern: a Verdant (×2) catch with Harmonic (×1.5) and Resonant (×2.5) becomes a much larger payout than a plain Common. Always sell after confirming the mutation tag—holding trophies only makes sense once your upgrade path is funded.

Instrument-locked mutations do not replace the global roll table; they add exclusive outcomes tied to that tool’s passive. Swap instruments when you are hunting a specific tag.

Global mutation tiers

S — Charged (×2) and Verdant (×2)

Charged is the premium global mutation for raw sell value at ×2, with a steep roll (community notes place it near 1 in 250). Farm during Stormy or high-activity weather when you can, and keep Luck food active.

Verdant also lands at ×2 but is gated behind Forest Spirit’s Lyre. Treat Lyre sessions as dedicated Verdant hunts. If your mid-game kit already includes the Lyre from Fenna’s quests, Verdant becomes one of the most reliable high multipliers before endgame passives.

A — Metallic (×1.8) and Runic (×1.5)

Metallic (about 1 in 120) is the best unrestricted mid-high multiplier for general farming. It appears often enough to matter on long Grove or Bluestone loops.

Runic matches Mossy’s ×1.5 but comes from Deepchord. Once Pell’s quest is done and Deepchord is equipped, Runic turns every cavern and mid-band session into a mutation farm. Prefer Deepchord over older tools whenever you are selling for Ballad or Keytaria money.

B — Mossy (×1.5) and Wooden (×1.3)

Mossy and Wooden share the common roll band (about 1 in 60 each). Mossy is strictly better on sell price; Wooden is still a welcome upgrade over a clean catch. Do not rearrange your whole loadout for Wooden alone—let it appear naturally while you chase Metallic and Charged.

Situational — instrument exclusives beyond Verdant/Runic

• Mothdust (Mothwing) — endgame sell monster at ×3 class value; prioritize Mothwing when you can clear its bands.
• Thorned (Keytaria) — lower multiplier than Verdant/Charged but exclusive; useful when Keytaria is already your Resonance-correct tool.
• Other named exclusives (for example Songstruck in some community tables) can rival or beat Charged—verify the live tooltip before you plan a farm around them.

Variant tiers

Variants stack on top of mutations and can appear together.

S — Resonant (×2.5, ~0.5%)

Rare and enormous. A Resonant roll on any strong mutation is a jackpot sell. There is no reliable force method beyond Luck stacking, Pale Moon / Songfall windows, and patience. When Resonant appears, sell unless you are collecting for a personal trophy and already own your next instrument.

A — Harmonic (×1.5, ~2%)

Common enough to plan around, strong enough to change session EV. Harmonic plus Metallic or Verdant is a standard money spike. Keep bag space clear so you do not accidentally discard tagged catches.

B — Melodic (×1.25)

Smallest variant multiplier, highest relative frequency among the three. Melodic still beats a clean sell and stacks with everything else. Treat it as free value, not a reason to idle in a weak spawn.

Farming priorities by goal

Chime rush for Violin / Deepchord / Ballad: Equip the highest Resonance tool you own that also enables a strong passive (Lyre or Deepchord mid-game; Mothwing late). Cook Rich Tea or Hearty Rich Tea, add Luck tea if chasing rares, then sell every mutated catch. See cooking recipes.

Dex completion: Mutations are secondary. Use area-correct Resonance from the areas guide and only swap to mutation instruments after the species is logged.

Mutation hunting: Stack Luck (Violin early, Soaring Tone or endgame tools later), Fourleaf or Starlit clover teas, and night weathers when Pale Moon or Songfall is up. Murkmoss-related foods that boost mutation chance help when available.

Weather and food synergy

Stormy weather is widely associated with livelier Scroom activity; Pale Moon and Songfall (night) favor rarer encounters. Pair those windows with Lucky dishes and your best Luck instrument. Sell-value dishes do not increase mutation odds—they amplify the payout when a mutation finally drops. Split sessions: one block for odds, one block for selling with Rich active if timers do not overlap well.

What not to do

• Do not refuse Metallic sells while waiting only for Charged; Metallic funds the next instrument.
• Do not equip a mutation instrument whose Resonance cannot reach the pool you are standing in.
• Do not ignore variants—Resonant alone can out-earn a mediocre mutation.
• Do not skip instrument tiers thinking mutations replace gear. Gear enables the pool; mutations multiply the sell.
