Paladin's Demon Arms ★★★

Taken all the way down to base materials, one Paladin's Demon Arms is 2 crafting steps deep and needs 2 intermediates — High Mythrite Ingot ×3 and Eikon Iron Ingot ×2 — which resolve to 8 distinct raw materials totalling 43 units, plus 30 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,293 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 13 Fire Cluster, 8 Earth Cluster, 6 Wind Cluster and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 60, Blacksmith to Lv 60 and Goldsmith to Lv 60 — so no single class can finish it unaided.

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

Of the intermediates, High Mythrite Ingot has the widest use: 150 recipes call for it, spanning seven of the eight crafting classes.
