Crowsbeak Hammer

Taken all the way down to base materials, one Crowsbeak Hammer is 3 crafting steps deep and needs 5 intermediates — Clove Oil ×1, Iron Ingot ×1, Undyed Cotton Cloth ×1 and 2 others — which resolve to 4 distinct raw materials totalling 10 units, plus 10 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 647 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 3 Fire Shard, 2 Earth Shard, 2 Lightning Shard and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 26, Carpenter to Lv 25, Alchemist to Lv 14 and Weaver to Lv 13 — so no single class can finish it unaided.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Crowsbeak Hammer is itself consumed by 1 further recipe, all of them Blacksmith recipes.
