True Linen Hat of Healing ★★★

Taken all the way down to base materials, one True Linen Hat of Healing is 3 crafting steps deep and needs 5 intermediates — True Linen ×2, Grade 3 Reisui of Mind ×1, Ground Sloth Leather ×1 and 2 others — which resolve to 13 distinct raw materials totalling 28 units, plus 23 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,333 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 6 Lightning Cluster, 6 Wind Cluster, 5 Wind Crystal and 3 other kinds.

The chain crosses four disciplines — Weaver to Lv 70, Alchemist to Lv 70, Leatherworker to Lv 70 and Goldsmith to Lv 68 — so no single class can finish it unaided.

7 of the 13 raw materials come out of the ground, and 3 of them are time-gated: Gyr Abanian Spring Water (10:00, 22:00), Hingan Flax (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Twinthread has the widest use: 109 recipes call for it, spanning six of the eight crafting classes.
