Leather Bags ★

Taken all the way down to base materials, one Leather Bags is 2 crafting steps deep and needs 3 intermediates — Pterodactyl Leather ×3, Darksteel Nugget ×1 and Silk Thread ×1 — which resolve to 5 distinct raw materials totalling 12 units, plus 18 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 768 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 8 Earth Cluster, 4 Wind Cluster, 3 Fire Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 60, Blacksmith to Lv 50 and Weaver to Lv 50 — so no single class can finish it unaided.

4 of the 5 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.
