Swamp Eel

Swamp Eel is a quest item that can be found by fishing in Swamp Caves. It is obtained through normal fishing rather than from combat or looting, making it a location-specific catch tied to the swamp cave biome.

Because it is a quest item, it is primarily something to hold onto until it is needed for a task. If you are exploring Swamp Caves, fishing is the relevant way to obtain it, so bringing the right fishing setup and spending time at the water there is the straightforward way to get one. Beyond that, its value comes from being part of quest progression rather than from crafting or direct combat use.
