Grandmaster Sprinkler

The Grandmaster Sprinkler is the top-end Prismatic gear from the Gear Shop, added in the Cooking Update, and its stats justify the name. Every new plant in its radius gets massively boosted crop size (a 4× size multiplier, +3 when stacking additively with other sprinkler types), higher mutation chances, and faster growth, all running for a 10-minute window. It even feeds your pets, not by cutting ability cooldowns but by effectively adding 4 kg of weight to boost their passive.

At 1,000,000,000 Sheckles (or 279 Robux) this is unapologetically an endgame item. For a casual plot it is overkill and a waste of a billion coins, because you cannot replant fast enough during the 10 minutes to exploit that 4× size on enough crops to recoup the price.

Where it shines is a dense, high-value farm that mass-plants exactly when the sprinkler activates. If you can flood the radius with premium seeds in one cycle, the combined size, mutation and growth boost — plus the pet weight bump — pays for itself quickly. Buy it only once your Sheckle income is comfortably in the billions and your planting routine is tight.
