Ceremonial Flat Brush ★★★

Taken all the way down to base materials, one Ceremonial Flat Brush is 2 crafting steps deep and needs 4 intermediates — Octahedrite Nugget ×3, Diatryma Felt ×2, Grade 3 Gemsap of Intelligence ×2 and 1 other — which resolve to 13 distinct raw materials totalling 41 units, plus 50 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,473 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 12 Lightning Cluster, 9 Earth Cluster, 9 Fire Cluster and 3 other kinds.

The chain crosses three disciplines — Alchemist to Lv 100, Blacksmith 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: Cochineal Pigment (6:00, 18:00), Fulgurite (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Octahedrite Nugget has the widest use: 67 recipes call for it, spanning seven of the eight crafting classes.
