Dorpokkur Kiln

Taken all the way down to base materials, one Dorpokkur Kiln is 2 crafting steps deep and needs 3 intermediates — Cut Stone ×5, Manganese Ingot ×5 and Firewood ×1 — which resolve to 5 distinct raw materials totalling 59 units, plus 73 crystals.

That bill outweighs 13,079 of the 13,602 recipes tracked here and 2,117 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 57 are burned by the intermediates, so the real crystal cost is 48 Fire Crystal, 16 Wind Shard, 8 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Goldsmith to Lv 90, Blacksmith to Lv 86 and Carpenter to Lv 12 — so no single class can finish it unaided.

All 5 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, Manganese Ingot has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
