Radiant Star

The Radiant Star is a craftable Hardmode non-consumable dagger that is an upgrade to the Prismalline. It shoots a projectile that is affected by gravity and cannot pass through walls. Shortly after it is thrown, it explodes and emits 3 gravity-defying copies of itself which deal half of the base damage. Hitting an enemy with the explosion will cause fallen, hallowed, and astral stars to rain down on the enemy.

Performing a stealth strike with the Radiant Star will cause the next dagger thrown to split into 6 copies and emit a larger, lingering explosion.

The Radiant Star also has a rare item variant called the Quasar that drops from Astrum Deus.
