Amateur's Dalmatica

Taken all the way down to base materials, one Amateur's Dalmatica is 3 crafting steps deep and needs 2 intermediates — Undyed Hempen Cloth ×2 and Hempen Yarn ×5 — which resolve to 2 distinct raw materials totalling 7 units, plus 7 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 557 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 6 Lightning Shard and 1 Wind Shard.

Every step is Weaver work, from a Lv 1 intermediate up to the Lv 10 finish, so one class covers the whole chain.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Undyed Hempen Cloth has the widest use: 66 recipes call for it, spanning five of the eight crafting classes.
