Mountain Chromite Maul

Taken all the way down to base materials, one Mountain Chromite Maul is 2 crafting steps deep and needs 2 intermediates — Mountain Chromite Ingot ×3 and Ginseng Lumber ×1 — which resolve to 3 distinct raw materials totalling 23 units, plus 47 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 956 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 32 Fire Crystal, 8 Wind Crystal and 7 Earth Crystal.

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

All 3 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, Mountain Chromite Ingot has the widest use: 65 recipes call for it, spanning five of the eight crafting classes.
