Gomphotherium Brais of Healing

Taken all the way down to base materials, one Gomphotherium Brais of Healing is 2 crafting steps deep and needs 5 intermediates — Gomphotherium Leather ×2, Grade 1 Gemsap of Mind ×2, Rroneek Serge ×2 and 2 others — which resolve to 10 distinct raw materials totalling 34 units, plus 72 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,651 of the 1,844 Leatherworker ones, and 4,464 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, 16 Lightning Crystal, 8 Fire Crystal and 2 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 97, Weaver to Lv 96, Blacksmith to Lv 94 and Alchemist to Lv 93 — so no single class can finish it unaided.

6 of the 10 raw materials match a gathering node, none of them timed; the other 4 come from vendors, drops or content this site does not track.

Of the intermediates, Cobalt Tungsten Ingot has the widest use: 105 recipes call for it, spanning six of the eight crafting classes.
