Olive

The Olive is an uncommon, multi-harvest crop added during the Smithing Event, and that multi-harvest trait is the heart of its economics. Uncommon rarity normally points to a cheap seed and a small individual sell price, but a plant that keeps producing without replanting changes the math: you pay the seed cost once, then collect repeatedly, so the real return is measured over the plant's lifetime rather than a single pull. That stretches a low base value into something genuinely worthwhile if you leave it in the ground.

Its standout feature is an unusually broad typing. The Olive is classified as Leafy, Sweet, Sour, Fruit and Tropical all at once, which means it catches buffs from an exceptionally wide range of type-targeted pets and tools. That makes it an efficient anchor for mutation stacking, since almost any specialized booster you own will touch it in some way.

Because it is limited to the Smithing Event, the seed cannot be rebought freely once the event ends, so it carries scarcity value. For progression, slot the Olive in as an early-to-mid passive earner: plant it, layer broad buffs, and let the repeated harvests quietly compound.
