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. If an ability truly stops responding after an update, rejoin the server to re-register it.

突变参考

Starfall

触发事件：Starfall Griffin

Vine

触发事件：Plant Rush Golem

突变攻略

如何选对突变

最强突变不只看倍率，还要看可控性、成本，以及目标种子值不值得承接这个喷雾或事件时间。

最佳免费目标

Honeycomb 是最强事件限定突变，但依赖 Bee Swarm。在线时保持地块种满，不要把整套配置都押在稀有事件上。

最实用喷雾

Rainbow 仍是第一个实用后期喷雾，因为它能在 Gear Shop 获得，并让 Outer Ring 种子先吃到 95x。

最高付费上限

Fire、Bubblegum 和 Cosmic 倍率高于 Rainbow，但现金成本只适合用在最高单价种子上。

中期过渡选择

Void 和 Radioactive 是从 Wet 到后期的桥。先用在 Middle Ring 高价种子上，再考虑高阶喷雾。

常见问题

怎么拿到 Rainbow 突变？

Rainbow（5×）来自 Galaxy 天气事件（每轮约 4% 触发，单株 1% Roll 中），综合有效概率约 0.04%。想省时间可以在 Gear Shop 花 $1T 现金或 279 Robux 买 Rainbow Spray，直接喷到任意植物上。

怎么拿到 Honeycomb 突变？

Honeycomb（6.5×）只来自 Bee Swarm 事件（每轮约 0.5% 触发，单株 1.5% Roll 中），商店里没有 Honeycomb Spray。把地块全种满、保持在线，等 Bee Swarm 触发。

最强的突变是哪个？

Honeycomb（6.5×）倍率最高，其次是 Rainbow（5×）。但 Rainbow 更实用，因为可以花 $1T 直接买 Rainbow Spray。后期最稳的高收益组合是：Outer Ring 上的 Transcended 种子 + Rainbow。

可以洗掉突变再换一个更好的吗？

可以。在 Gear Shop 花 $1M 现金或 19 Robux 买 Acid Spray，能清掉植物当前的突变。只在你买得起替换喷雾时再用。

Build A Ring Farm 的突变能叠加吗？

多数情况下不能。每株植物只带一个突变，新突变会覆盖旧的。例外是两个宠物突变：Starfall Griffin 的 Starfall（4×）和 Plant Rush Golem 的 Vine（3×），它们会叠在已有突变之上。这种叠加是相加不是相乘，所以 Fire 加 Starfall 是 14× 而不是 40×。突变倍率和圆环倍率、现金倍率之间则是相乘——Outer Ring（×19）配 Rainbow（×5）等于 ×95。

为什么我的突变不生效？

通常有三个原因。1）槽位规则：每株植物只能有一个突变——新喷雾会覆盖旧突变，而低档喷雾不能直接替换更强的突变，需要先用 Acid Spray（$1M）清除。2）概率：事件突变每株只有 0.5–8% 的 Roll 概率，大部分农场没变是预期内的。3）宠物被动：Hydra 和 Mammoth 的突变升级以 10 分钟为周期且基于概率。如果更新后技能确实卡住了，重新进服即可重新注册。
