Ale Tap

Taken all the way down to base materials, one Ale Tap is 2 crafting steps deep and needs 3 intermediates — Dwarven Mythril Ingot ×2, Titanbronze Ingot ×2 and Titanbronze Nugget ×1 — which resolve to 5 distinct raw materials totalling 25 units, plus 49 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,056 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

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

The chain crosses two disciplines — Blacksmith to Lv 78 and Goldsmith to Lv 76 — 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, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
