Gomphotherium Doublet of Gathering

Taken all the way down to base materials, one Gomphotherium Doublet of Gathering is 3 crafting steps deep and needs 5 intermediates — Gomphotherium Leather ×2, Rroneek Serge ×2, Br'aax Leather ×1 and 2 others — which resolve to 7 distinct raw materials totalling 30 units, plus 72 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,521 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 32 Earth Crystal, 24 Wind Crystal and 16 Lightning Crystal.

The chain crosses three disciplines — Leatherworker to Lv 97, Weaver to Lv 96 and Goldsmith to Lv 94 — so no single class can finish it unaided.

4 of the 7 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
