Spiked Mythril Labrys

Taken all the way down to base materials, one Spiked Mythril Labrys is 2 crafting steps deep and needs 4 intermediates — Steel Ingot ×3, Boar Leather ×1, Mythril Ingot ×1 and 1 other — which resolve to 6 distinct raw materials totalling 17 units, plus 26 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 757 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 15 Fire Shard, 8 Earth Shard and 3 Wind Shard.

The chain crosses three disciplines — Blacksmith to Lv 39, Leatherworker to Lv 33 and Carpenter to Lv 32 — so no single class can finish it unaided.

5 of the 6 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

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