Eikon Leather Corselet of Striking ★★★

Taken all the way down to base materials, one Eikon Leather Corselet of Striking is 3 crafting steps deep and needs 6 intermediates — Grade 1 Strength Dissolvent ×3, Eikon Leather ×2, Crawler Silk ×1 and 3 others — which resolve to 15 distinct raw materials totalling 44 units, plus 42 crystals.

That bill outweighs 12,337 of the 13,602 recipes tracked here and 1,797 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 37 are burned by the intermediates, so the real crystal cost is 11 Earth Cluster, 9 Wind Cluster, 5 Fire Cluster and 4 other kinds.

The chain crosses five disciplines — Leatherworker to Lv 60, Alchemist to Lv 60, Blacksmith to Lv 60, Goldsmith to Lv 60 and Weaver to Lv 57 — so no single class can finish it unaided.

9 of the 15 raw materials come out of the ground, and 5 of them are time-gated: Lumythrite Ore (2:00, 14:00), Smithsonite Ore (8:00, 20:00) and 3 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Crawler Silk has the widest use: 178 recipes call for it, spanning five of the eight crafting classes.
