Highland Composite Chimney

Taken all the way down to base materials, one Highland Composite Chimney is 3 crafting steps deep and needs 5 intermediates — Dark Chestnut Lumber ×3, Titanium Nugget ×3, Roof Tile ×2 and 2 others — which resolve to 9 distinct raw materials totalling 52 units, plus 53 crystals.

That bill outweighs 12,890 of the 13,602 recipes tracked here and 1,366 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 42 are burned by the intermediates, so the real crystal cost is 18 Water Shard, 12 Fire Crystal, 12 Wind Crystal and 2 other kinds.

The chain crosses four disciplines — Armorer to Lv 60, Blacksmith to Lv 54, Carpenter to Lv 54 and Alchemist to Lv 41 — 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, Varnish has the widest use: 114 recipes call for it, spanning four of the eight crafting classes.
