Saurian Gloves of Casting ★★★

Taken all the way down to base materials, one Saurian Gloves of Casting is 2 crafting steps deep and needs 3 intermediates — Terminus Putty ×2, Hippogryph Leather ×1 and Saurian Leather ×1 — which resolve to 7 distinct raw materials totalling 9 units, plus 12 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 665 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 9 are burned by the intermediates, so the real crystal cost is 4 Earth Cluster, 3 Earth Crystal, 2 Water Cluster and 2 other kinds.

The chain crosses two disciplines — Leatherworker to Lv 50 and Alchemist to Lv 50 — so no single class can finish it unaided.

2 of the 7 raw materials come out of the ground, and one of them is time-gated: Shroud Tea Leaves (2:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Hippogryph Leather has the widest use: 131 recipes call for it, spanning seven of the eight crafting classes.
