Where can you find a giant shell?
In the Forest of Erinyes and Mort regions, players will run into puzzles that center on oversized shells and explosive tricks. This particular shell is found near the Hydro Archon statue in the Erinyes Forest, beside Markoth Station. The surrounding layout blends environmental storytelling with a quick timing challenge, inviting players to think about placement, timing, and reward all at once. To claim the chest, a small nearby mechanism must first be activated to reveal the missing water level crystal and unlock the path ahead.
To obtain the chest, players must complete a nearby puzzle that yields the water level crystal missing from the scene.
How to solve the first riddle and get the crystal
Just to the right of the sink area, a floating crystal becomes visible. Adjacent to it sits a device that lets travelers learn to wield the xenochrome spherical octopus’s energy on land. Interact with this device and channel power toward the floating crystal. With that action, platforms will appear above the ground—forming the only correct route to the chest and the crystal. Note that these platforms vanish soon after, and the device cannot be restarted until the timer runs out, so players must move decisively.
A suggested path is helpful to stay on track. The directions below can be followed to reach the destination:
- Three platforms straight ahead;
- Two to the left;
- Two straight;
- One to the left.
When the journey ends, a regular chest will appear. The rewards are modest, typically a small cache of source stones and the missing crystal needed to progress further.
How to open a shell and activate crystals
With the crystal in hand, return to the sink area. Since there are no hydrogranums nearby, players must try a different approach. If the game tutorial has been completed, it’s clear that the giant grenades can be opened with a few well-timed strikes. Hit the stone near the sink several times, then break it, triggering a rain of elemental energy. Crystals activate, and a precious chest plus a handful of small slimes appear nearby for loot and practice in combat timing.
There are more sinks across Fontaine beyond this one. For example, discovering another giant shell may yield a treasure map that points toward hidden rewards across the region.
