Aetherial Conductor

Taken all the way down to base materials, one Aetherial Conductor is 2 crafting steps deep and needs 3 intermediates — AR-Caean Velvet ×1, Integral Lumber ×1 and Ophiotauros Leather ×1 — which resolve to 4 distinct raw materials totalling 15 units, plus 40 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 826 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 16 Earth Crystal, 16 Wind Crystal and 8 Lightning Crystal.

The chain crosses three disciplines — Leatherworker to Lv 88, Carpenter to Lv 88 and Weaver to Lv 88 — so no single class can finish it unaided.

3 of the 4 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Ophiotauros Leather has the widest use: 153 recipes call for it, spanning seven of the eight crafting classes.
