Arachne Culottes of Healing ★★★★

Taken all the way down to base materials, one Arachne Culottes of Healing is 2 crafting steps deep and needs 4 intermediates — Arachne Velveteen ×5, Hippogryph Leather ×2, Platinum Nugget ×1 and 1 other — which resolve to 7 distinct raw materials totalling 19 units, plus 36 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 977 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 15 Wind Cluster, 12 Lightning Cluster, 6 Earth Crystal and 2 other kinds.

The chain crosses three disciplines — Weaver to Lv 50, Goldsmith to Lv 50 and Leatherworker to Lv 50 — so no single class can finish it unaided.

3 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Platinum Ore (4:00) and Shroud Tea Leaves (2:00). The widest gap between consecutive opening times is 22 Eorzean hours, about 64 real-world minutes.

Of the intermediates, Hippogryph Leather has the widest use: 131 recipes call for it, spanning seven of the eight crafting classes.
