Everseeker's Saw ★★

Taken all the way down to base materials, one Everseeker's Saw is 2 crafting steps deep and needs 4 intermediates — Maraging Steel Ingot ×3, Alexandrian Plate ×2, Gargantua Leather ×1 and 1 other — which resolve to 9 distinct raw materials totalling 44 units, plus 50 crystals.

That bill outweighs 12,337 of the 13,602 recipes tracked here and 1,595 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 18 Earth Cluster, 12 Fire Cluster, 8 Earth Crystal and 3 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 100, Alchemist to Lv 100, Armorer to Lv 100 and Leatherworker to Lv 98 — so no single class can finish it unaided.

4 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Alexandrian Ore (6:00, 18:00), Harmonite Ore (6:00, 18:00) and 1 other. The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Gargantua Leather has the widest use: 89 recipes call for it, spanning five of the eight crafting classes.
