Potent Sleeping Potion

Taken all the way down to base materials, a batch of 3 Potent Sleeping Potion is 2 crafting steps deep and needs 1 intermediate — Quicksilver ×1 — which resolves to 3 distinct raw materials totalling 4 units, plus 13 crystals.

That bill outweighs 3,935 of the 13,602 recipes tracked here and 746 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 1 are burned by the intermediates, so the real crystal cost is 7 Water Shard and 6 Lightning Shard.

Every step is Alchemist work, from a Lv 1 intermediate up to the Lv 48 finish, so one class covers the whole chain.

2 of the 3 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Potent Sleeping Potion is itself consumed by 1 further recipe, all of them Alchemist recipes.
