Mythril Round Knife

Taken all the way down to base materials, one Mythril Round Knife is 2 crafting steps deep and needs 4 intermediates — Basilisk Whetstone ×1, Mahogany Lumber ×1, Mythril Ingot ×1 and 1 other — which resolve to 5 distinct raw materials totalling 9 units, plus 28 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 597 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 10 Wind Shard, 9 Earth Shard and 9 Fire Shard.

The chain crosses four disciplines — Blacksmith to Lv 42, Goldsmith to Lv 40, Carpenter to Lv 39 and Leatherworker to Lv 38 — so no single class can finish it unaided.

4 of the 5 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.
