Exarchic Bracelet of Healing ★★★★

Taken all the way down to base materials, one Exarchic Bracelet of Healing is 2 crafting steps deep and needs 4 intermediates — Grade 4 Mind Alkahest ×1, Sea Swallow Leather ×1, Silver Beech Lumber ×1 and 1 other — which resolve to 10 distinct raw materials totalling 24 units, plus 31 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 904 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 9 Wind Cluster, 7 Earth Crystal, 6 Ice Cluster and 3 other kinds.

The chain crosses four disciplines — Carpenter to Lv 80, Alchemist to Lv 80, Goldsmith 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), Silver Beech Log (6:00, 18:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 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.
