Lost Ark: What is the Key Swallowed By Mimic used for

With hidden quests, extra dungeons, world bosses, and more loot than you can handle, the free-to-play MMO Lost Ark contains more content than most players will be able to explore. Players will ultimately come across an item called a Key Swallowed by Mimic while managing the loot that is dropping over the country of Arkesia.

The Key Swallowed by Mimic is trash loot, unlike many other items that drop with no obvious use, only to be discovered later that it's an optional payment for an obscure NPC. It is impossible to deconstruct, and there are no viable turn-ins. The object does nothing but take up space until it is sold to a seller for one silver.

The item is thought to be made purely for amusement: the idea of mimics eating their own keys has comedic overtones, ensuring that their mouths cannot be shut. Nonetheless, the artifact has been clogging the pockets of adventurers who aren't sure what to do with the key, and the Nevatia Ruins of Ozhorn Hill aren't short on mimics.

This, paired with the vastness of Lost Ark, where things might have several functions, has irritated some players. Players can untangle themselves from the key's shackles by selling it to a vendor or simply dragging and dropping it off of their inventory to destroy it.
