Raised Wooden Deck

Taken all the way down to base materials, one Raised Wooden Deck is 3 crafting steps deep and needs 4 intermediates — Integral Lumber ×10, Red Pine Lumber ×6, Mortar ×4 and 1 other — which resolve to 5 distinct raw materials totalling 96 units, plus 200 crystals.

That bill outweighs 13,461 of the 13,602 recipes tracked here and 1,506 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 64 of those crystals go into the final step; the other 136 are burned by the intermediates, so the real crystal cost is 160 Wind Crystal, 32 Ice Crystal and 8 Water Shard.

The chain crosses two disciplines — Carpenter to Lv 90 and Alchemist to Lv 20 — 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, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
