Adamant Chakrams ★★

Taken all the way down to base materials, one Adamant Chakrams is 2 crafting steps deep and needs 3 intermediates — Tungsten Steel Ingot ×3, Pliable Glass Fiber ×2 and Dwarven Mythril Ingot ×1 — which resolve to 9 distinct raw materials totalling 42 units, plus 31 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,501 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 8 Earth Cluster, 8 Fire Cluster, 7 Fire Crystal and 2 other kinds.

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

4 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Sandalwood Sap (2:00, 14:00) and Tungsten Ore (10:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
