Altered Felt Hat

Taken all the way down to base materials, one Altered Felt Hat is 3 crafting steps deep and needs 4 intermediates — Mythril Ingot ×1, Undyed Felt ×1, Woolen Yarn ×1 and 1 other — which resolve to 6 distinct raw materials totalling 11 units, plus 24 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 737 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 13 Lightning Shard, 5 Wind Shard, 4 Fire Shard and 1 other kind.

The chain crosses three disciplines — Weaver to Lv 47, Blacksmith to Lv 38 and Alchemist to Lv 25 — so no single class can finish it unaided.

4 of the 6 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
