Dwarven Lignum Pole

Taken all the way down to base materials, one Dwarven Lignum Pole is 2 crafting steps deep and needs 4 intermediates — Dwarven Mythril Ingot ×2, Dwarven Mythril Nugget ×1, Growth Formula Kappa ×1 and 1 other — which resolve to 8 distinct raw materials totalling 24 units, plus 49 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 904 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 35 are burned by the intermediates, so the real crystal cost is 21 Wind Crystal, 14 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 76 — so no single class can finish it unaided.

6 of the 8 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.
