Manganese Helm of the Behemoth King

Taken all the way down to base materials, one Manganese Helm of the Behemoth King is 3 crafting steps deep and needs 5 intermediates — Manganese Ingot ×2, Bismuth Ingot ×1, Blue Zircon ×1 and 2 others — which resolve to 9 distinct raw materials totalling 30 units, plus 64 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,081 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 16 Wind Crystal, 8 Earth Crystal and 2 other kinds.

The chain crosses four disciplines — Armorer to Lv 86, Blacksmith to Lv 86, Goldsmith to Lv 86 and Alchemist to Lv 83 — so no single class can finish it unaided.

8 of the 9 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Manganese Ingot has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
