Heavy Crowsbeak Hammer

Taken all the way down to base materials, one Heavy Crowsbeak Hammer is 4 crafting steps deep and needs 6 intermediates — Crowsbeak Hammer ×1, Clove Oil ×2, Iron Ingot ×2 and 3 others — which resolve to 4 distinct raw materials totalling 15 units, plus 17 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 730 of the 1,932 Blacksmith ones, and 1 recipe nests deeper.

Only 5 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 7 Fire Shard, 4 Earth Shard, 2 Lightning Shard and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 29, 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.

Of the intermediates, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
