Diadochos Armlets of Healing ★★★★

Taken all the way down to base materials, one Diadochos Armlets of Healing is 3 crafting steps deep and needs 5 intermediates — Garnet Cotton ×2, Grade 8 Mind Alkahest ×2, Deinosuchus Leather ×1 and 2 others — which resolve to 10 distinct raw materials totalling 33 units, plus 46 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,541 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 16 Wind Crystal, 12 Lightning Cluster, 12 Wind Cluster and 2 other kinds.

The chain crosses four disciplines — Weaver to Lv 90, Alchemist to Lv 90, Leatherworker to Lv 90 and Goldsmith to Lv 88 — so no single class can finish it unaided.

6 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Field Mustard (10:00, 22:00), Lovingbloom (0:00, 12:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Star Quartz has the widest use: 157 recipes call for it, spanning seven of the eight crafting classes.
