Courtly Lover's Boots of Fending ★★★★

Taken all the way down to base materials, one Courtly Lover's Boots of Fending is 2 crafting steps deep and needs 4 intermediates — Grade 4 Gemsap of Vitality ×2, Mastodon Leather ×2, Claro Walnut Lumber ×1 and 1 other — which resolve to 9 distinct raw materials totalling 30 units, plus 38 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,521 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 12 Wind Cluster, 9 Earth Cluster, 8 Wind Crystal and 2 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 100, Alchemist to Lv 100, Weaver to Lv 100 and Carpenter to Lv 98 — so no single class can finish it unaided.

6 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Carnauba Leaf (4:00, 16:00), Urqopacha Flax (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, Claro Walnut Lumber has the widest use: 82 recipes call for it, spanning six of the eight crafting classes.
