Saurian Trousers ★★★

Taken all the way down to base materials, one Saurian Trousers is 2 crafting steps deep and needs 3 intermediates — Hippogryph Leather ×2, Saurian Leather ×2 and Terminus Putty ×2 — which resolve to 7 distinct raw materials totalling 13 units, plus 18 crystals.

That bill outweighs 6,426 of the 13,602 recipes tracked here and 788 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 6 Earth Cluster, 6 Earth Crystal, 3 Wind 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.
