Stump Stool

Taken all the way down to base materials, one Stump Stool is 2 crafting steps deep and needs 1 intermediate — Beeswax ×5 — which resolves to 2 distinct raw materials totalling 16 units, plus 7 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 675 of the 1,552 Carpenter ones, and 4,464 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 5 Water Shard, 1 Ice Shard and 1 Wind Shard.

The chain crosses two disciplines — Carpenter to Lv 13 and Alchemist to Lv 10 — so no single class can finish it unaided.

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

Stump Stool is itself consumed by 1 further recipe, all of them Armorer recipes.
