Darksteel Hook ★★

Taken all the way down to base materials, one Darksteel Hook is 2 crafting steps deep and needs 1 intermediate — Darksteel Nugget ×2 — which resolves to 1 distinct raw material totalling 6 units, plus 27 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 467 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 21 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 11 Fire Shard, 10 Earth Shard and 6 Fire Crystal.

Every step is Blacksmith work, from a Lv 50 intermediate up to the Lv 50 finish, so one class covers the whole chain.

The single raw material is gathered, and it is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Darksteel Hook is itself consumed by 1 further recipe, all of them Blacksmith recipes.
