Griffin

The Griffin entry carries one of the steepest figures on this list, a x50 multiplier, but it is sourced as a Limited divine pet rather than a passive weather effect, which changes how you actually get the bonus. It was released in the second half of the Beanstalk Event and pulled from the Skyroot Chest at just a 1% open chance, so simply obtaining the Griffin is the hard part.

In play the mutation is easy to spot: blue particles drawn toward the fruit, blue stars and grey circles ring the crop while the effect is active. As a pet-driven mutation it applies to crops within the Griffin's working range, meaning placement and uptime matter far more than waiting on the weather.

A x50 ceiling is elite territory, and because it stacks on top of growth variants and other environmental mutations in the summed value pool, a Griffin-touched Rainbow fruit can post some of the largest single-crop sales in the game. Whether it is worth chasing comes down to the 1% chest odds: the payoff is enormous, but the grind to roll the divine pet is genuinely long, so prioritize it only if you are already farming Skyroot Chests.
