Gargantuaskin Jacket of Striking

Taken all the way down to base materials, one Gargantuaskin Jacket of Striking is 2 crafting steps deep and needs 5 intermediates — Gargantua Leather ×2, Grade 1 Gemsap of Strength ×2, Ra'Kaznar Ingot ×2 and 2 others — which resolve to 10 distinct raw materials totalling 38 units, plus 72 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,745 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, 24 Fire Crystal, 8 Water Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 99, Blacksmith to Lv 98 and Alchemist to Lv 93 — so no single class can finish it unaided.

7 of the 10 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, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
