Paladin's Horde Arms ★★★

Taken all the way down to base materials, one Paladin's Horde Arms is 3 crafting steps deep and needs 4 intermediates — High Mythrite Ingot ×3, Eikon Iron Ingot ×1, Eikon Leather ×1 and 1 other — which resolve to 11 distinct raw materials totalling 43 units, plus 34 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,293 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 11 Earth Cluster, 11 Fire Cluster, 5 Wind Cluster and 3 other kinds.

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

6 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Lumythrite Ore (2:00, 14:00), Smithsonite Ore (8:00, 20:00) and 1 other. 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.
