Mythrite Claymore

Taken all the way down to base materials, one Mythrite Claymore is 2 crafting steps deep and needs 5 intermediates — Mythrite Nugget ×4, Archaeornis Leather ×1, Cedar Lumber ×1 and 2 others — which resolve to 7 distinct raw materials totalling 41 units, plus 30 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,468 of the 1,932 Blacksmith 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 15 Fire Crystal, 5 Earth Crystal, 4 Fire Shard and 2 other kinds.

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.

4 of the 7 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
