Heliodor Ring

Taken all the way down to base materials, one Heliodor Ring is 2 crafting steps deep and needs 2 intermediates — Heliodor ×1 and Mythril Ingot ×1 — which resolve to 2 distinct raw materials totalling 4 units, plus 16 crystals.

That bill outweighs 3,935 of the 13,602 recipes tracked here and 504 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 8 Fire Shard and 8 Wind Shard.

The chain crosses two disciplines — Goldsmith to Lv 40 and Blacksmith to Lv 38 — so no single class can finish it unaided.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

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