Deinosuchus Leather ★★★★

Nothing in this list is craftable in turn, so one Deinosuchus Leather is a single step: 7 units of material drawn from 2 base items, plus 6 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 598 of the 1,844 Leatherworker 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: Field Mustard (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Deinosuchus Leather is itself consumed by 33 further recipes, spanning four of the eight crafting classes.
