Mythrite Labrys

Taken all the way down to base materials, one Mythrite Labrys is 3 crafting steps deep and needs 8 intermediates — Mythrite Ingot ×3, Holy Cedar Lumber ×1, Mythrite Rivets ×1 and 5 others — which resolve to 10 distinct raw materials totalling 54 units, plus 46 crystals.

That bill outweighs 12,945 of the 13,602 recipes tracked here and 1,762 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 39 are burned by the intermediates, so the real crystal cost is 28 Fire Crystal, 6 Earth Crystal, 6 Water Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 53, Alchemist to Lv 52, Carpenter to Lv 52 and Leatherworker to Lv 52 — so no single class can finish it unaided.

7 of the 10 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 Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
