Masonwork Stove

Taken all the way down to base materials, one Masonwork Stove is 3 crafting steps deep and needs 5 intermediates — Cut Stone ×2, Mortar ×2, Steel Ingot ×2 and 2 others — which resolve to 7 distinct raw materials totalling 32 units, plus 22 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,738 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 10 Wind Shard, 7 Fire Shard, 4 Water Shard and 1 other kind.

The chain crosses four disciplines — Goldsmith to Lv 32, Blacksmith to Lv 26, Alchemist to Lv 20 and Carpenter to Lv 12 — so no single class can finish it unaided.

All 7 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, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
