The Clamstack is one of the many harvestables that can be found in the Frontier. They are often found in clusters and sometimes, by itself, similar to the Sandy Coral or the Shell. They are typically found on the coastlines of the Frontier, although it is possible to encounter it in zones located further inland within the Frontier. The locations of the Clamstacks include but are not limited to:

It is also possible for players to acquire the Clamstack as an 'uncommon' drop from Pirates and/or the Shellmouth.


The Clamstack is a stack of clams toppling on each other. As its description implies, it is part creature, and part plant, as evident by the clams and other unidentified coastal plants that makes up the harvestable. A white pearl can be seen in the center of an opened clam.

Currently, the Clamstack cannot be used in any shapes or forms in the game, Fantastic Frontier. It is simply sold to a selling vendor at a selling price of 2,500 gold.


  • While interacting with Joker Jenny in Topple Town, she will reference a small area known as Clamstack Cave that exists in the Frontier. This refers to the area that can be found in Ancient Forest, located near the lower parts of the Ancient Forest/Castle Bridge.
