Crystarium Stove

Taken all the way down to base materials, one Crystarium Stove is 3 crafting steps deep and needs 4 intermediates — Titanbronze Ingot ×6, Titanbronze Nugget ×3, Cobalt Joint Plate ×2 and 1 other — which resolve to 5 distinct raw materials totalling 51 units, plus 96 crystals.

That bill outweighs 12,830 of the 13,602 recipes tracked here and 1,731 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 83 are burned by the intermediates, so the real crystal cost is 49 Fire Crystal, 21 Wind Crystal, 10 Fire Shard and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 76, Goldsmith to Lv 76 and Armorer to Lv 44 — so no single class can finish it unaided.

All 5 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, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
