Mountain Chromite Creasing Knife

Taken all the way down to base materials, one Mountain Chromite Creasing Knife is 2 crafting steps deep and needs 3 intermediates — Mountain Chromite Ingot ×2, Annite Whetstone ×1 and Ginseng Lumber ×1 — which resolve to 4 distinct raw materials totalling 21 units, plus 47 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 874 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 16 Wind Crystal and 7 Earth Crystal.

The chain crosses three disciplines — Blacksmith to Lv 91, Carpenter to Lv 91 and Goldsmith to Lv 86 — so no single class can finish it unaided.

All 4 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, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
