Seed mound routes
Cattail seeds in Oceanus
Cattail seeds start a garden cycle that supplies an ingredient used by multiple Crossroads recipes.
Seed mounds in Oceanus on the Underworld route; dig with the Silver Spade, then grow the seed at the Crossroads.
Repeat Oceanus searches when more Cattail is required, then cycle each seed through planting and harvest. Seed mounds are variable, and each seed produces a garden crop only after growth completes. Spend the crop on the target recipe and reassess the remaining ingredients.
Stop targeting Cattail once your harvested amount covers the next recipe requirement; move to another missing ingredient.
