Mythril Gorget

Taken all the way down to base materials, one Mythril Gorget is 2 crafting steps deep and needs 2 intermediates — Mythril Ingot ×2 and Toad Leather ×1 — which resolve to 3 distinct raw materials totalling 8 units, plus 17 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 742 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 11 Fire Shard, 4 Wind Shard and 2 Earth Shard.

The chain crosses three disciplines — Goldsmith to Lv 35, Blacksmith to Lv 38 and Leatherworker to Lv 26 — so no single class can finish it unaided.

One intermediate outranks the result: Mythril Ingot is a Lv 38 Blacksmith recipe feeding a Lv 35 craft, so that step, not the last one, is the real gate.

2 of the 3 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.
