Obelisk Head ★★

Taken all the way down to base materials, one Obelisk Head is 3 crafting steps deep and needs 2 intermediates — Darksteel Ingot ×1 and Darksteel Nugget ×4 — which resolve to 2 distinct raw materials totalling 21 units, plus 15 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 874 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 2 Fire Cluster and 1 Earth Cluster.

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

1 of the 2 raw materials come out of the ground, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Obelisk Head is itself consumed by 1 further recipe, all of them Blacksmith recipes.
