Giant Centipedes

Description
Be warned! While the Giant Centripede looks easy to slay, a simply clumsy and disgusting insect grown too big, its poison is the worst of all beasts, causing death within less than a minute! Fight these beasts with fire, or you will surely perish a fast and painful death.

They can be found in dungeons and caves.
