Cobalt Tungsten Needle

Taken all the way down to base materials, one Cobalt Tungsten Needle is 3 crafting steps deep and needs 4 intermediates — Cobalt Tungsten Ingot ×2, Mountain Linen ×1, Pink Beryl ×1 and 1 other — which resolve to 5 distinct raw materials totalling 24 units, plus 55 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,346 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal, 23 Fire Crystal and 8 Lightning Crystal.

The chain crosses three disciplines — Goldsmith to Lv 95, Blacksmith to Lv 94 and Weaver to Lv 92 — so no single class can finish it unaided.

All 5 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, Cobalt Tungsten Ingot has the widest use: 105 recipes call for it, spanning six of the eight crafting classes.
