Marble Flooring ★★

Taken all the way down to base materials, one Marble Flooring is 3 crafting steps deep and needs 2 intermediates — Mortar ×4 and Distilled Water ×4 — which resolve to 5 distinct raw materials totalling 34 units, plus 10 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,771 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 8 Water Shard, 1 Fire Cluster and 1 Wind Cluster.

The chain crosses two disciplines — Goldsmith to Lv 50 and Alchemist to Lv 20 — so no single class can finish it unaided.

4 of the 5 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
