Black Horn Staff

Taken all the way down to base materials, one Black Horn Staff is 2 crafting steps deep and needs 1 intermediate — Eye of Wind ×1 — which resolves to 2 distinct raw materials totalling 3 units, plus 12 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 451 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 2 are burned by the intermediates, so the real crystal cost is 7 Wind Shard and 5 Fire Shard.

Every step is Goldsmith work, from a Lv 23 intermediate up to the Lv 44 finish, so one class covers the whole chain.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Eye of Wind has the widest use: 4 recipes call for it, spanning three of the eight crafting classes.
