The Cosmic Elemental is a Pre-Hardmode enemy that spawns in the Cavern. They behave the same as Granite Elementals, flying through walls and rolling into a ball when damaged in Expert Mode. Upon death, the Cosmic Elemental has a chance to drop a number of rare swords that are otherwise not obtainable through conventional means. The Cosmic Elemental always applies the Confused debuff on hit players for three seconds.
