Serpentskin Armguards of Striking

Taken all the way down to base materials, one Serpentskin Armguards of Striking is 3 crafting steps deep and needs 5 intermediates — Amphiptere Leather ×2, Grade 1 Strength Dissolvent ×1, Titanium Ingot ×1 and 2 others — which resolve to 9 distinct raw materials totalling 33 units, plus 41 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,636 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 17 Fire Crystal, 15 Earth Crystal, 5 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 58, Blacksmith to Lv 56 and Alchemist to Lv 53 — so no single class can finish it unaided.

6 of the 9 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
