High Steel Pliers

Taken all the way down to base materials, one High Steel Pliers is 3 crafting steps deep and needs 2 intermediates — High Steel Ingot ×3 and High Steel Nugget ×4 — which resolve to 3 distinct raw materials totalling 32 units, plus 27 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,223 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal and 3 Earth Crystal.

Every step is Blacksmith work, from a Lv 61 intermediate up to the Lv 62 finish, so one class covers the whole chain.

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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
