Fairy Event#Fairy Upgrades

The Fairy Upgrades page covers the progression track inside the Fairy Event, an Event Weather run that premiered on August 30th and ended on September 13th, 2025. Where the base fairy weather simply sprinkles a Glimmering mutation onto a random crop, the Upgrades layer is the persistent-investment side of the event: spending event resources to permanently improve how the fairy mechanics perform for you.

Because the event lasted only about two weeks, the upgrade track was a sprint, not a marathon. Every day inside that window mattered, since upgrades typically gate stronger fairy effects, better mutation odds or faster reward generation behind tiered costs that you can only pay with event-specific currency earned during the run.

For profit, the playbook was to rush the earliest upgrade tiers first, because they compound: an early boost to your fairy yield pays itself back over the remaining days of the event. Anyone who treated the September 13th cutoff as a hard deadline and front-loaded their grind walked away with maxed upgrades, while latecomers lost access entirely once the event closed and the currency stopped dropping.
