Bronze Haubergeon

Taken all the way down to base materials, one Bronze Haubergeon is 3 crafting steps deep and needs 4 intermediates — Bronze Rings ×3, Undyed Hempen Cloth ×1, Bronze Ingot ×3 and 1 other — which resolve to 3 distinct raw materials totalling 11 units, plus 10 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 555 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 4 Ice Shard, 3 Fire Shard, 2 Lightning Shard and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 6, Weaver to Lv 2 and Blacksmith to Lv 1 — so no single class can finish it unaided.

All 3 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, Bronze Ingot has the widest use: 76 recipes call for it, spanning six of the eight crafting classes.
