Eulmoran Marble Flooring

Taken all the way down to base materials, one Eulmoran Marble Flooring is 3 crafting steps deep and needs 3 intermediates — Hard Mudstone Whetstone ×8, Mortar ×4 and Distilled Water ×4 — which resolve to 5 distinct raw materials totalling 48 units, plus 70 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 2,043 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 55 Wind Crystal, 8 Water Shard and 7 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 78 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.
