Sky Pirate's Vest of Aiming ★★

Taken all the way down to base materials, one Sky Pirate's Vest of Aiming is 3 crafting steps deep and needs 7 intermediates — Cloud Cloth ×2, Grade 1 Dexterity Dissolvent ×2, Amphiptere Leather ×1 and 4 others — which resolve to 16 distinct raw materials totalling 37 units, plus 33 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,651 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 7 Lightning Crystal, 6 Lightning Cluster, 5 Earth Crystal and 5 other kinds.

The chain crosses four disciplines — Weaver to Lv 60, Blacksmith to Lv 60, Leatherworker to Lv 58 and Alchemist to Lv 53 — so no single class can finish it unaided.

12 of the 16 raw materials come out of the ground, and 4 of them are time-gated: Cloud Cotton Boll (0:00, 4:00, 8:00, 12:00, 16:00, 20:00), Sphalerite (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and 2 others. The widest gap between consecutive opening times is 2 Eorzean hours, about 6 real-world minutes.

Of the intermediates, Crawler Silk has the widest use: 178 recipes call for it, spanning five of the eight crafting classes.
