Sky Pirate's Boots of Striking ★★

Taken all the way down to base materials, one Sky Pirate's Boots of Striking is 2 crafting steps deep and needs 4 intermediates — Pterodactyl Leather ×2, Amphiptere Leather ×1, Grade 1 Strength Dissolvent ×1 and 1 other — which resolve to 10 distinct raw materials totalling 23 units, plus 23 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 1,208 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 Fire Crystal and 2 other kinds.

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

5 of the 10 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, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
