Forager's Sledgehammer ★★★

Taken all the way down to base materials, one Forager's Sledgehammer is 3 crafting steps deep and needs 4 intermediates — Horn Glue ×1, Treated Spruce Lumber ×1, Wolfram Ingot ×1 and 1 other — which resolve to 7 distinct raw materials totalling 26 units, plus 16 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,087 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 6 Wind Crystal, 4 Fire Cluster, 3 Water Shard and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 50, Carpenter to Lv 50 and Alchemist to Lv 30 — so no single class can finish it unaided.

3 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Ferberite (3:00) and Spruce Log (9:00). The widest gap between consecutive opening times is 18 Eorzean hours, about 53 real-world minutes.

Of the intermediates, Wolfram Ingot has the widest use: 107 recipes call for it, spanning five of the eight crafting classes.
