Exarchic Boots of Aiming ★★★★

Taken all the way down to base materials, one Exarchic Boots of Aiming is 3 crafting steps deep and needs 5 intermediates — Grade 4 Dexterity Alkahest ×2, Thylacoleo Leather ×2, Dwarven Cotton ×1 and 2 others — which resolve to 9 distinct raw materials totalling 29 units, plus 37 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,478 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 12 Wind Cluster, 9 Earth Cluster, 7 Lightning Crystal and 3 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 80, Alchemist to Lv 80, Carpenter to Lv 80 and Weaver to Lv 78 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Hard Water (4:00, 16:00), Silver Beech Log (6:00, 18:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
