Oasis Wooden Awning

Taken all the way down to base materials, one Oasis Wooden Awning is 3 crafting steps deep and needs 3 intermediates — Ash Lumber ×4, Iron Ingot ×4 and Iron Rivets ×2 — which resolve to 2 distinct raw materials totalling 24 units, plus 12 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 904 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 6 Fire Shard, 5 Wind Shard and 1 Ice Shard.

The chain crosses two disciplines — Carpenter to Lv 16 and Blacksmith to Lv 18 — so no single class can finish it unaided.

One intermediate outranks the result: Iron Rivets is a Lv 18 Blacksmith recipe feeding a Lv 16 craft, so that step, not the last one, is the real gate.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.
