Eikon Leather Armguards of Casting ★★★

Taken all the way down to base materials, one Eikon Leather Armguards of Casting is 3 crafting steps deep and needs 7 intermediates — Eikon Leather ×2, Grade 1 Intelligence Dissolvent ×2, Crawler Silk ×1 and 4 others — which resolve to 16 distinct raw materials totalling 47 units, plus 46 crystals.

That bill outweighs 12,643 of the 13,602 recipes tracked here and 1,810 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 41 are burned by the intermediates, so the real crystal cost is 9 Earth Cluster, 9 Fire Crystal, 8 Wind Cluster and 4 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 60, Alchemist to Lv 60, Weaver to Lv 60 and Blacksmith to Lv 56 — so no single class can finish it unaided.

12 of the 16 raw materials come out of the ground, and 4 of them are time-gated: Frost Cotton Boll (6:00, 18:00), Wattle Bark (2:00, 14:00) and 2 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

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