Dwarven Lignum Lance

Taken all the way down to base materials, one Dwarven Lignum Lance is 2 crafting steps deep and needs 5 intermediates — Lignum Vitae Lumber ×2, Deepgold Ingot ×1, Dwarven Mythril Ingot ×1 and 2 others — which resolve to 9 distinct raw materials totalling 27 units, plus 55 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,005 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 41 are burned by the intermediates, so the real crystal cost is 28 Wind Crystal, 13 Fire Crystal, 7 Ice Crystal and 1 other kind.

The chain crosses four disciplines — Carpenter to Lv 78, Blacksmith to Lv 78, Goldsmith to Lv 78 and Alchemist to Lv 75 — so no single class can finish it unaided.

7 of the 9 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
