Mythril Claws

Taken all the way down to base materials, one Mythril Claws is 3 crafting steps deep and needs 4 intermediates — Fish Glue ×1, Mythril Plate ×1, Oak Lumber ×1 and 1 other — which resolve to 3 distinct raw materials totalling 14 units, plus 29 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 699 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 17 Fire Shard, 4 Earth Shard, 4 Ice Shard and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 39, Armorer to Lv 38, Carpenter to Lv 32 and Alchemist to Lv 10 — so no single class can finish it unaided.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

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