Kotetsu Replica

Taken all the way down to base materials, one Kotetsu Replica is 4 crafting steps deep and needs 10 intermediates — Oroshigane Ingot ×3, Wolfram Ingot ×3, Beech Lumber ×1 and 7 others — which resolve to 14 distinct raw materials totalling 49 units, plus 48 crystals.

That bill outweighs 12,749 of the 13,602 recipes tracked here and 1,719 of the 1,932 Blacksmith ones, and 1 recipe nests deeper.

Only 7 of those crystals go into the final step; the other 41 are burned by the intermediates, so the real crystal cost is 20 Fire Crystal, 6 Fire Cluster, 6 Lightning Crystal and 5 other kinds.

The chain crosses five disciplines — Blacksmith to Lv 64, Carpenter to Lv 61, Goldsmith to Lv 61, Alchemist to Lv 52 and Weaver to Lv 52 — so no single class can finish it unaided.

One intermediate outranks the result: Oroshigane Ingot is a Lv 64 Blacksmith recipe feeding a Lv 63 craft, so that step, not the last one, is the real gate.

12 of the 14 raw materials come out of the ground, and 2 of them are time-gated: Dravanian Mistletoe (0:00, 12:00) and Ferberite (3:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.
