Rroneek Serge Doublet of Crafting

Taken all the way down to base materials, one Rroneek Serge Doublet of Crafting 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 1,408 of the 1,968 Weaver 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 24 Earth Crystal, 24 Lightning Crystal and 24 Wind Crystal.

The chain crosses three disciplines — Weaver to Lv 97, Leatherworker 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.
