Build A Ring Farm 的 Rainbow Spray 怎麼拿、值不值得

• Gear Shop

  The stall ticks on a 5-minute clock and a manual restock costs 35 Robux (stock.ts). Rainbow Spray is NOT in stock.ts's rareStockIds — only Cosmic, Bubblegum, and Fire are — so the dataset treats it as regular stock, not a rotation prize.

  gears.ts rainbow-spray record (barf.fandom.com/wiki/Gear_Shop) and the matching mutations.ts rainbow shopPriceCash / shopPriceRobux; the hotbar frame at 332.0s in i9k0dVQL0Lc shows twelve owned copies, which is what a Gear Shop hoard looks like

• Plant Rush shop

  The cheapest guaranteed Rainbow Spray in the recording — but the panel second itself carries a burned-in subtitle, so the page publishes the reading without shipping that frame.

  shop panel read at 397.25s in i9k0dVQL0Lc: the Tokens tab lists Radioactive Spray 9,000 · Rainbow Spray 14,000 · Cosmic Spray 25,000 tokens. No gears.ts or mutations.ts field carries a Rainbow token price, so this stays a panel reading, not a dataset number

• Compost Machine

  The reward popup at 300.8s in i9k0dVQL0Lc is the on-camera payout: three cards, Super Fertilizer x5, Rainbow Spray, Super Pet Treat x5. Which machine tier paid it is a live dispute — see rainbowSprayDisputes.

  Compost Machine odds panel at 190.0s in UJz_Fu5QjOI (2026-05-26 build), Next Tier (Overgrown Compost) column, same panel, 2026-05-26 build: Rainbow Spray 20% — the only published compost table that lists it

• Night Market Pass

  A tier reward, not a roll: reaching the tier pays the item. The free track pays one, which makes this the only no-cost, no-luck route the dataset records.

  season-passes.ts Night Market table (revision 2317): tier 12 premium and tier 32 free pay one Rainbow Spray each

• Trucker event

  The grade itself depends on how the Trucker scores your farm, and the pool is drawn from, so this is a lottery on top of a lottery. The recording's 8:06 narration walks the Trucker stall without pulling a Rainbow Spray.

  events.ts truckerGrades: Rainbow Spray sits in the S+ grade pool (9 rewards). No per-reward odds are published

• Galaxy weather event

  This applies the Rainbow mutation to a standing crop — you get the 5x, not a spray to store. It is the only route that costs nothing and is still worth modelling, which is why the page prints the arithmetic.

  events.ts galaxy record: eventChance 4% x chancePerRoll 1% per plant = the effective rate shown in this row; mutations.ts rainbow trigger is Galaxy with perRollChance 1

這張表就是本站能查證的全部內容。沒有任何一列填了臆測的百分比；沒有公布機率的途徑會直接寫「無公布機率」，而不會估一個數字。

Galaxy 進行中每 1,000 株的期望突變株數。這是對公布機率所做的算術，不是某次遊玩結果。

這條途徑給你的是地裡那一株的 5 倍，不是一支能儲存或送人的噴霧，所以它解決的不是同一個問題。它是唯一既不花錢又值得事先規劃的途徑，因此本頁把數字攤開寫，而不是用「稀有事件」含糊帶過。

• i9k0dVQL0Lc (MistyLemon, 2026-06-04) advises that on a Transcendent seed you should 'not have a spray below radioactive or rainbow'. That is one player's spending rule, not a game mechanic: no source publishes a tier gate, and the dataset prices Rainbow at 5x against Radioactive's 3x without ranking either as a requirement.
• The same recording calls the composter payout 'already kind of good' and 'not a bad mutation'. Value judgements stay out of the tables; the page prints the multiplier, the price, and the published odds and lets the reader decide.
• WzgPy1oBY4Y and the other guide-channel narrations reused by /cosmic-spray describe the token shop as the reliable spray route without ever naming a Rainbow price. Absence of a spoken number is why 14,000 tokens rests on the panel reading alone.
