Cosmic Shiv

The Cosmic Shiv is a craftable post-Moon Lord shortsword that is the direct upgrade to the Elemental Shiv. When used, it releases homing cosmic orbs that travel in a sine-wave pattern. Upon contacting an enemy, the orbs spawn several cosmic blades and cause galaxy stars to rain down.

Trivia

 * Despite being themed similarly to Cosmilite weaponry, it is in a later tier than those items due to requiring Darksun Fragments to craft.
