Mountain Chromite Blade

Taken all the way down to base materials, one Mountain Chromite Blade is 2 crafting steps deep and needs 4 intermediates — Mountain Chromite Ingot ×3, Annite Whetstone ×1, Integral Lumber ×1 and 1 other — which resolve to 6 distinct raw materials totalling 33 units, plus 63 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,266 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 24 Wind Crystal and 7 Earth Crystal.

The chain crosses three disciplines — Blacksmith to Lv 91, Goldsmith to Lv 91 and Carpenter to Lv 88 — so no single class can finish it unaided.

All 6 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, Integral Lumber has the widest use: 114 recipes call for it, spanning seven of the eight crafting classes.
