Augmented Ekplexis ★★

Taken all the way down to base materials, one Augmented Ekplexis is 2 crafting steps deep and needs 3 intermediates — Tungsten Steel Ingot ×3, Crimson Firesand ×2 and Prismatic Ingot ×2 — which resolve to 9 distinct raw materials totalling 53 units, plus 46 crystals.

That bill outweighs 12,925 of the 13,602 recipes tracked here and 1,759 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 12 Water Crystal, 10 Fire Cluster, 7 Earth Crystal and 3 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 80, Goldsmith to Lv 80 and Alchemist to Lv 71 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Prismstone (4:00, 16:00) and Tungsten Ore (10:00, 22:00). The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Tungsten Steel Ingot has the widest use: 113 recipes call for it, spanning six of the eight crafting classes.
