Ronkan Fireplace

Taken all the way down to base materials, one Ronkan Fireplace is 3 crafting steps deep and needs 4 intermediates — Annite Whetstone ×3, Triplite ×3, Firewood ×1 and 1 other — which resolve to 5 distinct raw materials totalling 45 units, plus 132 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,996 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 64 of those crystals go into the final step; the other 68 are burned by the intermediates, so the real crystal cost is 98 Wind Crystal, 32 Fire Crystal, 1 Ice Shard and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 90 and Carpenter to Lv 12 — so no single class can finish it unaided.

All 5 raw materials are gathered, and one of them is time-gated: Raw Triplite (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
