Dwarven Cotton Petasos of Healing

Taken all the way down to base materials, one Dwarven Cotton Petasos of Healing is 3 crafting steps deep and needs 4 intermediates — Dwarven Cotton ×2, Grade 1 Mind Alkahest ×1, Sea Swallow Leather ×1 and 1 other — which resolve to 7 distinct raw materials totalling 18 units, plus 41 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 951 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 21 Lightning Crystal, 7 Earth Crystal, 7 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Weaver to Lv 78, Leatherworker to Lv 78 and Alchemist to Lv 73 — so no single class can finish it unaided.

4 of the 7 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
