Aetherial Amplifier

Taken all the way down to base materials, one Aetherial Amplifier is 2 crafting steps deep and needs 3 intermediates — Red Pine Lumber ×1, Saiga Leather ×1 and Snow Linen ×1 — which resolve to 4 distinct raw materials totalling 15 units, plus 39 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 839 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 16 Lightning Crystal, 15 Wind Crystal and 8 Earth Crystal.

The chain crosses three disciplines — Weaver to Lv 85, Carpenter to Lv 84 and Leatherworker to Lv 84 — 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, Saiga Leather has the widest use: 83 recipes call for it, spanning seven of the eight crafting classes.
