Gryphonskin Eyepatch ★★

Taken all the way down to base materials, one Gryphonskin Eyepatch is 3 crafting steps deep and needs 5 intermediates — Darksteel Ingot ×1, Hard Hippogryph Leather ×1, Silk Thread ×1 and 2 others — which resolve to 9 distinct raw materials totalling 33 units, plus 19 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,636 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 6 Earth Crystal, 6 Fire Crystal, 3 Lightning Crystal and 3 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 50, Blacksmith to Lv 50 and Weaver to Lv 50 — so no single class can finish it unaided.

4 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
