Hingan Watchtower (Mokuzo)

Taken all the way down to base materials, one Hingan Watchtower (Mokuzo) is 3 crafting steps deep and needs 4 intermediates — Beech Lumber ×4, Hardsilver Nugget ×2, Mythrite Ingot ×2 and 1 other — which resolve to 6 distinct raw materials totalling 48 units, plus 37 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,342 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 23 Wind Crystal, 12 Fire Crystal and 2 Ice Crystal.

The chain crosses three disciplines — Carpenter to Lv 61, Goldsmith to Lv 54 and Blacksmith to Lv 52 — so no single class can finish it unaided.

All 6 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, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
