Highland Rounded Chimney

Taken all the way down to base materials, one Highland Rounded Chimney is 2 crafting steps deep and needs 2 intermediates — Titanium Nugget ×4 and Cut Stone ×3 — which resolve to 4 distinct raw materials totalling 40 units, plus 36 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,447 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 22 Fire Crystal, 9 Wind Shard and 5 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 60 and Goldsmith to Lv 30 — so no single class can finish it unaided.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
