Gajaskin Vest of Striking

Taken all the way down to base materials, one Gajaskin Vest of Striking is 2 crafting steps deep and needs 4 intermediates — Gaja Leather ×3, Dwarven Mythril Ingot ×1, High Durium Nugget ×1 and 1 other — which resolve to 7 distinct raw materials totalling 31 units, plus 61 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,562 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 39 Earth Crystal, 15 Fire Crystal and 7 Wind Crystal.

The chain crosses two disciplines — Leatherworker to Lv 81 and Blacksmith to Lv 81 — so no single class can finish it unaided.

5 of the 7 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
