Storm Blue Interior Wall

Taken all the way down to base materials, one Storm Blue Interior Wall is 3 crafting steps deep and needs 4 intermediates — Cut Stone ×6, Dwarven Mythril Nugget ×6, Mortar ×4 and 1 other — which resolve to 6 distinct raw materials totalling 68 units, plus 82 crystals.

That bill outweighs 13,264 of the 13,602 recipes tracked here and 1,563 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 68 are burned by the intermediates, so the real crystal cost is 42 Wind Crystal, 18 Wind Shard, 8 Water Shard and 2 other kinds.

The chain crosses two disciplines — Alchemist to Lv 80 and Goldsmith to Lv 78 — 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, Dwarven Mythril Nugget has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
