Rarefied Mythrite Needle

Taken all the way down to base materials, one Rarefied Mythrite Needle is 2 crafting steps deep and needs 3 intermediates — Mythrite Nugget ×2, Basilisk Whetstone ×1 and Cedar Lumber ×1 — which resolve to 4 distinct raw materials totalling 18 units, plus 21 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 1,038 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 14 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 7 Wind Crystal and 5 Wind Shard.

The chain crosses three disciplines — Goldsmith to Lv 54, Blacksmith to Lv 51 and Carpenter to Lv 51 — so no single class can finish it unaided.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
