Archeo Kingdom Round Brush ★★

Taken all the way down to base materials, one Archeo Kingdom Round Brush is 2 crafting steps deep and needs 4 intermediates — Sterling Silver Ingot ×3, Blackseed Cotton Cloth ×2, Grade 2 Gemsap of Intelligence ×2 and 1 other — which resolve to 13 distinct raw materials totalling 40 units, plus 50 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,466 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 15 Wind Cluster, 12 Lightning Cluster, 9 Fire Cluster and 2 other kinds.

The chain crosses three disciplines — Alchemist to Lv 100, Goldsmith to Lv 100 and Weaver to Lv 100 — so no single class can finish it unaided.

8 of the 13 raw materials come out of the ground, and 3 of them are time-gated: Blackseed Cotton Boll (4:00, 16:00), Fine Silver Ore (10:00, 22:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Blackseed Cotton Cloth has the widest use: 46 recipes call for it, spanning seven of the eight crafting classes.
