Bronze War Axe

Taken all the way down to base materials, one Bronze War Axe is 2 crafting steps deep and needs 2 intermediates — Bronze Ingot ×2 and Maple Lumber ×1 — which resolve to 3 distinct raw materials totalling 9 units, plus 5 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 597 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

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

The chain crosses two disciplines — Blacksmith to Lv 3 and Carpenter 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.

Bronze War Axe is itself consumed by 1 further recipe, all of them Blacksmith recipes.
