Sky Pirate's Boots of Aiming ★★

Taken all the way down to base materials, one Sky Pirate's Boots of Aiming is 2 crafting steps deep and needs 4 intermediates — Pterodactyl Leather ×2, Amphiptere Leather ×1, Grade 1 Dexterity Dissolvent ×1 and 1 other — which resolve to 9 distinct raw materials totalling 22 units, plus 23 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,157 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 6 Earth Cluster, 5 Earth Crystal, 4 Water Crystal and 2 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 60, Goldsmith to Lv 54 and Alchemist to Lv 53 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Amphiptere Leather has the widest use: 108 recipes call for it, spanning seven of the eight crafting classes.
