Unseen Spirit

The Unseen Spirit is an early-War Mode enemy spawned in the Dungeon or The Underworld. They resemble and act like normal Dungeon Spirits. The Unseen Spirit behaves in a same way as normal Dungeon Spirits. They are spawned by killing any monster with 1000 or more in the Dungeon or The Underworld in War Mode at a 100% chance. They are capable of moving through blocks and will chase the player at full speed until it dies. The Unseen Spirit has a bigger chance of spawning during a Blood Moon or a Solar Eclipse.
