Ironwood Cane

Taken all the way down to base materials, one Ironwood Cane is 3 crafting steps deep and needs 4 intermediates — Blue Zircon ×2, Ironwood Lumber ×2, Snow Linen ×1 and 1 other — which resolve to 4 distinct raw materials totalling 33 units, plus 80 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,116 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 64 are burned by the intermediates, so the real crystal cost is 64 Wind Crystal, 8 Ice Crystal and 8 Lightning Crystal.

The chain crosses three disciplines — Carpenter to Lv 86, Goldsmith to Lv 86 and Weaver to Lv 84 — 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, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
