War Chest

Taken all the way down to base materials, one War Chest is 2 crafting steps deep and needs 3 intermediates — Dark Chestnut Lumber ×4, Cedar Lumber ×2 and Hardsilver Nugget ×2 — which resolve to 4 distinct raw materials totalling 42 units, plus 44 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,260 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 30 Wind Crystal, 7 Ice Shard and 7 Wind Shard.

The chain crosses two disciplines — Carpenter to Lv 54 and Goldsmith to Lv 54 — 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, Hardsilver Nugget has the widest use: 88 recipes call for it, spanning seven of the eight crafting classes.
