Rarefied Cobalt Tungsten Scimitars

Taken all the way down to base materials, one Rarefied Cobalt Tungsten Scimitars is 3 crafting steps deep and needs 4 intermediates — Cobalt Tungsten Ingot ×2, Magnesia Whetstone ×1, Pink Beryl ×1 and 1 other — which resolve to 5 distinct raw materials totalling 23 units, plus 55 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 956 of the 1,932 Blacksmith 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 Fire Crystal, 16 Wind Crystal, 8 Water Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 95, Alchemist to Lv 95 and Goldsmith to Lv 94 — 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.
