Rroneek Serge Trousers of Crafting

Taken all the way down to base materials, one Rroneek Serge Trousers of Crafting is 2 crafting steps deep and needs 4 intermediates — Gomphotherium Leather ×2, Rroneek Serge ×2, Br'aax Leather ×1 and 1 other — which resolve to 6 distinct raw materials totalling 28 units, plus 64 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,333 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 32 Lightning Crystal, 24 Earth Crystal and 8 Wind Crystal.

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

3 of the 6 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, Br'aax Leather has the widest use: 91 recipes call for it, spanning seven of the eight crafting classes.
