Corrosive

Corrosive is a mid-tier acid mutation delivering a respectable x40 sale multiplier, comfortably above the small flat boosts while staying below the triple-digit event tags. That makes it one of the more useful everyday multipliers to land, especially when you can pile it onto crops that already carry value.

It is easy to identify thanks to a rich, layered visual: part of the crop turns green, green particles drop from the bottom, and particles sweep across the crop in a corroding wash. This places it squarely in the toxic/acid family alongside other green-dripping effects, but the sweeping animation gives it its own distinct look so you can tell it apart from plain poison tags.

Because crop mutations multiply together, x40 becomes genuinely powerful when stacked with size, Rainbow, and a weather mutation on the same plant, turning a single specimen into a serious payout. As a chase target it sits in the sweet spot: high enough to meaningfully move your Sheckle totals, yet common enough through its trigger that it is worth deliberately farming rather than waiting on luck. Prioritize applying it to your largest, most-mutated produce.
