Exarchic Shoes of Healing ★★★★

Taken all the way down to base materials, one Exarchic Shoes of Healing is 2 crafting steps deep and needs 4 intermediates — Grade 4 Mind Alkahest ×2, Saffron Cloth ×2, Sea Swallow Leather ×1 and 1 other — which resolve to 10 distinct raw materials totalling 30 units, plus 37 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,408 of the 1,968 Weaver ones, and 4,464 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 Lightning Cluster, 12 Wind Cluster, 7 Earth Crystal and 2 other kinds.

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

5 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Hard Water (4:00, 16:00), Raindrop Cotton Boll (10:00, 22:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Sea Swallow Leather has the widest use: 124 recipes call for it, spanning six of the eight crafting classes.
