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 652 of the 1,552 Carpenter 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 Wind Crystal, 8 Earth Crystal, 8 Lightning Crystal and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 85, Leatherworker to Lv 84 and Weaver 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.
