Courtly Lover's Armguards of Striking ★★★★

Taken all the way down to base materials, one Courtly Lover's Armguards of Striking is 2 crafting steps deep and needs 4 intermediates — Grade 4 Gemsap of Strength ×2, Mastodon Leather ×2, Gargantua Leather ×1 and 1 other — which resolve to 10 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 Earth Crystal and 2 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 100, Alchemist to Lv 100 and Weaver to Lv 100 — 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: 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, Gargantua Leather has the widest use: 89 recipes call for it, spanning five of the eight crafting classes.
