Sharlayan Reflecting Pool

Taken all the way down to base materials, one Sharlayan Reflecting Pool is 3 crafting steps deep and needs 3 intermediates — Magnesia Whetstone ×5, Mortar ×4 and Distilled Water ×4 — which resolve to 6 distinct raw materials totalling 48 units, plus 112 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 64 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 40 Water Crystal, 32 Fire Crystal, 32 Wind Crystal and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 96 and Alchemist to Lv 95 — so no single class can finish it unaided.

All 6 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.
