Oasis Flooring

Taken all the way down to base materials, one Oasis Flooring is 2 crafting steps deep and needs 2 intermediates — Beeswax ×6 and Walnut Lumber ×6 — which resolve to 2 distinct raw materials totalling 36 units, plus 22 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,184 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 14 Wind Shard, 6 Water Shard and 2 Ice Shard.

The chain crosses two disciplines — Carpenter to Lv 26 and Alchemist to Lv 10 — so no single class can finish it unaided.

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

Of the intermediates, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
