Mythril-barreled Musketoon

Taken all the way down to base materials, one Mythril-barreled Musketoon is 2 crafting steps deep and needs 5 intermediates — Black Firesand ×1, Mahogany Lumber ×1, Mythril Ingot ×1 and 2 others — which resolve to 10 distinct raw materials totalling 19 units, plus 27 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 804 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 11 Fire Shard, 8 Earth Shard, 5 Wind Shard and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 41, Carpenter to Lv 39, Leatherworker to Lv 38 and Alchemist to Lv 32 — so no single class can finish it unaided.

9 of the 10 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
