Glade Cobblestone Wall

Taken all the way down to base materials, one Glade Cobblestone Wall is 2 crafting steps deep and needs 2 intermediates — Roof Tile ×30 and Cut Stone ×10 — which resolve to 5 distinct raw materials totalling 160 units, plus 84 crystals.

That bill outweighs 13,536 of the 13,602 recipes tracked here and 2,192 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 24 of those crystals go into the final step; the other 60 are burned by the intermediates, so the real crystal cost is 42 Wind Shard, 30 Water Shard and 12 Fire Shard.

The chain crosses two disciplines — Goldsmith to Lv 32 and Alchemist to Lv 11 — 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, Cut Stone has the widest use: 103 recipes call for it, spanning six of the eight crafting classes.
