Halberd of the Round ★★★

Taken all the way down to base materials, one Halberd of the Round is 2 crafting steps deep and needs 4 intermediates — Luminous Fiber ×3, Platinum Ingot ×3, High Mythrite Ingot ×2 and 1 other — which resolve to 13 distinct raw materials totalling 70 units, plus 41 crystals.

That bill outweighs 13,294 of the 13,602 recipes tracked here and 1,460 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 15 Wind Cluster, 12 Fire Cluster, 6 Ice Cluster and 3 other kinds.

The chain crosses four disciplines — Carpenter to Lv 60, Alchemist to Lv 60, Blacksmith to Lv 60 and Goldsmith to Lv 50 — so no single class can finish it unaided.

6 of the 13 raw materials come out of the ground, and 5 of them are time-gated: Crystallized Sap (8:00, 20:00), Lumythrite Ore (2:00, 14:00) and 3 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
