Vanity Mirror

Taken all the way down to base materials, one Vanity Mirror is 3 crafting steps deep and needs 4 intermediates — Clear Glass Lens ×2, Manasilver Nugget ×2, Titanbronze Nugget ×2 and 1 other — which resolve to 7 distinct raw materials totalling 26 units, plus 52 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,562 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 35 Wind Crystal, 10 Water Shard and 7 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 78 and Alchemist to Lv 28 — so no single class can finish it unaided.

All 7 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Vanity Mirror is itself consumed by 1 further recipe, all of them Carpenter recipes.
