Mythrite Katzbalger

Taken all the way down to base materials, one Mythrite Katzbalger is 2 crafting steps deep and needs 5 intermediates — Darksteel Nugget ×2, Mythrite Nugget ×2, Archaeornis Leather ×1 and 2 others — which resolve to 8 distinct raw materials totalling 32 units, plus 26 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,223 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 15 Fire Crystal, 5 Earth Crystal, 3 Water Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 51, Alchemist to Lv 51, Carpenter to Lv 51 and Leatherworker to Lv 51 — so no single class can finish it unaided.

5 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00) and Darksteel Ore (1:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Darksteel Nugget has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
