Bronze Barbut

Taken all the way down to base materials, one Bronze Barbut is 3 crafting steps deep and needs 4 intermediates — Bronze Plate ×1, Bronze Rivets ×1, Copper Ingot ×1 and 1 other — which resolve to 2 distinct raw materials totalling 12 units, plus 8 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 580 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 4 Fire Shard, 2 Ice Shard, 1 Earth Shard and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 10, Blacksmith to Lv 3 and Goldsmith to Lv 1 — 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.

Bronze Barbut is itself consumed by 1 further recipe, all of them Armorer recipes.
