How do I get the Rainbow mutation in Build A Ring Farm?

Rainbow (5x) comes from Galaxy weather events (about 4% chance per cycle, 1% per-plant roll). The effective rate is 0.04% per plant per cycle. You can also buy Rainbow Spray from the Gear Shop for $1T cash or 279 Robux to apply it instantly to any plant.

How do I get the Honeycomb mutation in Build A Ring Farm?

Honeycomb (6.5x) is the strongest free event mutation and comes exclusively from Bee Swarm weather events (about 0.5% chance per cycle, 1.5% per-plant roll). There is no Honeycomb Spray in the Gear Shop, so you must stay online and wait for Bee Swarm to fire. Keep all plots planted to maximize your chances.

What is the best mutation in Build A Ring Farm?

Eclipse (12x) is the highest multiplier, applied by the Eclipse Spray at $50Qn — the most expensive item in the Gear Shop. Below it, Fire and Arcane tie at 10x, then Carnival (9.5x) and Bubblegum (9x). Rainbow (5x) is still much easier to get via the $1T Rainbow Spray. For practical endgame farming, use the strongest spray you can afford on Outer Ring Exotic or Transcended seeds.

Can I remove a mutation and reapply a better one?

Yes. Buy Acid Spray from the Gear Shop for $1M cash or 19 Robux. It removes the current mutation from a plant so you can spray or wait for a better one. Only use this when you can actually afford the replacement spray.

Can mutations stack in Build A Ring Farm?

Usually not — a plant holds one mutation and a new one overwrites the old. The exception is pet-applied mutations: the Starfall Griffin (Starfall, 4x) and the Plant Rush Golem (Vine, 3x) add their mutation on top of an existing one. That stacking is additive, not multiplicative, so a Fire plant that picks up Starfall sells at 14x rather than 40x. Mutation multipliers do multiply against the ring and cash multipliers — Outer Ring (19x) with Rainbow (5x) is a combined 95x.

Why are my mutations not working in Build A Ring Farm?

Three usual causes. 1) Slot rules: each plant holds one mutation — new sprays overwrite the old one, and a cheaper spray won't replace a stronger mutation without Acid Spray ($1M) first. 2) Odds: event mutations roll at only 0.5–8% per plant, so most of your farm staying unmutated each event is expected. 3) Pet passives: Hydra and Mammoth mutation upgrades cycle every 10 minutes and are chance-based.

突變攻略

如何選對突變

最強突變不只看倍率，還要看可控性、成本，以及目標種子值不值得承接這個噴霧或事件時間。

最佳免費目標

Honeycomb 是最強事件限定突變，但依賴 Bee Swarm。線上時保持地塊種滿，不要把整套配置都押在稀有事件上。

最實用噴霧

Rainbow 仍是第一個實用後期噴霧，因為它能在 Gear Shop 獲得，並讓 Outer Ring 種子先吃到 95x。

最高付費上限

Fire、Bubblegum 和 Cosmic 倍率高於 Rainbow，但現金成本只適合用在最高單價種子上。

中期過渡選擇

Void 和 Radioactive 是從 Wet 到後期的橋。先用在 Middle Ring 高價種子上，再考慮高階噴霧。

常見問題

怎麼拿到 Rainbow 突變？

Rainbow（5×）來自 Galaxy 天氣事件（每輪約 4% 觸發，單株 1% Roll 中），綜合有效機率約 0.04%。想省時間可以在 Gear Shop 花 $1T 現金或 279 Robux 買 Rainbow Spray，直接噴到任意植物上。

怎麼拿到 Honeycomb 突變？

Honeycomb（6.5×）只來自 Bee Swarm 事件（每輪約 0.5% 觸發，單株 1.5% Roll 中），商店裡沒有 Honeycomb Spray。把地塊全種滿、保持上線，等 Bee Swarm 觸發。

最強的突變是哪一個？

Honeycomb（6.5×）倍率最高，其次是 Rainbow（5×）。但 Rainbow 更實用，因為可以花 $1T 直接買 Rainbow Spray。後期最穩的高收益組合是：Outer Ring 上的 Transcended 種子 + Rainbow。

可以洗掉突變再換一個更好的嗎？

可以。在 Gear Shop 花 $1M 現金或 19 Robux 買 Acid Spray，就能清掉植物目前的突變。只在你買得起替換噴霧時再用。

Build A Ring Farm 的突變能疊加嗎？

多數情況下不能。每株植物只帶一個突變，新突變會覆蓋舊的。例外是兩個寵物突變：Starfall Griffin 的 Starfall（4×）和 Plant Rush Golem 的 Vine（3×），它們會疊在已有突變之上。這種疊加是相加不是相乘，所以 Fire 加 Starfall 是 14× 而不是 40×。突變倍率和圓環倍率、現金倍率之間則是相乘——Outer Ring（×19）配 Rainbow（×5）等於 ×95。

為什麼我的突變沒有作用？

通常有三個原因。1）槽位規則：每株植物只能有一個突變——新噴霧會覆蓋舊突變，而低檔噴霧不能直接取代更強的突變，需要先用 Acid Spray（$1M）清除。2）機率：事件突變每株只有 0.5–8% 的 Roll 機率，大部分農場沒變是預期內的。3）寵物被動：Hydra 和 Mammoth 的突變升級以 10 分鐘為週期且基於機率。如果更新後技能確實卡住了，重新進伺服器即可重新註冊。
