Perfect Dark

The Perfect Dark is a craftable Pre-Hardmode broadsword that also drops from The Hive Mind. When swung, it fires a small spherical projectile that deals damage to the target hit and sticks to the first surface it touches. After sticking onto a surface for 4 seconds, it explodes - emitting purple particles and dealing damage to all enemies in a small radius.
