Echo Drops

Nothing in this list is craftable in turn, so a batch of 3 Echo Drops is a single step: 3 units of material drawn from 3 base items, plus 3 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 426 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Nothing in the data consumes Echo Drops: it is one of 3 end products among the 4 Alchemist recipes at Lv 22.
