Mythril Bhuj

Taken all the way down to base materials, one Mythril Bhuj is 2 crafting steps deep and needs 4 intermediates — Mythril Ingot ×2, Electrum Ingot ×1, Steel Ingot ×1 and 1 other — which resolve to 5 distinct raw materials totalling 16 units, plus 26 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 750 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, 7 Wind Shard and 4 Earth Shard.

The chain crosses three disciplines — Blacksmith to Lv 40, Goldsmith to Lv 42 and Carpenter to Lv 25 — so no single class can finish it unaided.

One intermediate outranks the result: Electrum Ingot is a Lv 42 Goldsmith recipe feeding a Lv 40 craft, so that step, not the last one, is the real gate.

All 5 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.
