Mythril Wristlets

Taken all the way down to base materials, one Mythril Wristlets is 3 crafting steps deep and needs 2 intermediates — Mythril Ingot ×3 and Mythril Rings ×2 — which resolve to 1 distinct raw material totalling 9 units, plus 27 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 764 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 15 Fire Shard, 8 Ice Shard and 4 Wind Shard.

The chain crosses three disciplines — Goldsmith to Lv 35, Blacksmith to Lv 38 and Armorer to Lv 37 — 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.

Its single raw material is gathered, and no spot for it is timed, so nothing in the tree waits on the Eorzean clock.
