Weak Silencing Potion

Taken all the way down to base materials, a batch of 3 Weak Silencing Potion is 2 crafting steps deep and needs 1 intermediate — Quicksilver ×1 — which resolves to 3 distinct raw materials totalling 4 units, plus 4 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 3 of those crystals go into the final step; the other 1 are burned by the intermediates, so the real crystal cost is 3 Water Shard and 1 Lightning Shard.

Every step is Alchemist work, from a Lv 1 intermediate up to the Lv 22 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.

Weak Silencing Potion is itself consumed by 1 further recipe, all of them Alchemist recipes.
