Hingan Watchtower (Nanpu)

Taken all the way down to base materials, one Hingan Watchtower (Nanpu) is 3 crafting steps deep and needs 5 intermediates — Koppranickel Ingot ×4, Varnish ×4, Dark Chestnut Lumber ×2 and 2 others — which resolve to 7 distinct raw materials totalling 66 units, plus 71 crystals.

That bill outweighs 13,242 of the 13,602 recipes tracked here and 2,140 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 64 are burned by the intermediates, so the real crystal cost is 36 Wind Crystal, 32 Water Shard and 3 Fire Crystal.

The chain crosses three disciplines — Goldsmith to Lv 63, Carpenter to Lv 54 and Alchemist to Lv 41 — so no single class can finish it unaided.

6 of the 7 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, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
