Oasis Ornate Fence

Taken all the way down to base materials, one Oasis Ornate Fence is 3 crafting steps deep and needs 5 intermediates — Mortar ×30, Cut Stone ×20, Cobalt Ingot ×5 and 2 others — which resolve to 7 distinct raw materials totalling 215 units, plus 218 crystals.

That bill outweighs 13,568 of the 13,602 recipes tracked here and 2,207 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 48 of those crystals go into the final step; the other 170 are burned by the intermediates, so the real crystal cost is 109 Wind Shard, 60 Water Shard and 49 Fire Shard.

The chain crosses three disciplines — Goldsmith to Lv 50, Blacksmith to Lv 42 and Alchemist to Lv 20 — 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
