Spirits of Salt ★★

Nothing in this list is craftable in turn, so one Spirits of Salt is a single step: 3 units of material drawn from 2 base items, plus 21 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 426 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

1 of the 2 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Spirits of Salt is itself consumed by 1 further recipe, all of them Alchemist recipes.
