Red Brick Kitchen

Taken all the way down to base materials, one Red Brick Kitchen is 2 crafting steps deep and needs 4 intermediates — Firebricks ×12, Titanbronze Ingot ×5, Lignum Vitae Lumber ×3 and 1 other — which resolve to 6 distinct raw materials totalling 82 units, plus 84 crystals.

That bill outweighs 13,417 of the 13,602 recipes tracked here and 1,573 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 70 are burned by the intermediates, so the real crystal cost is 35 Fire Crystal, 21 Wind Crystal, 12 Water Shard and 4 other kinds.

The chain crosses three disciplines — Alchemist to Lv 80, Carpenter to Lv 78 and Blacksmith to Lv 76 — 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, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
