The Vampire is a Hard Mode enemy that spawns as part of the Solar Eclipse event. They are capable of changing forms into a bat when they are far away from or unable to reach the player, making it hard to escape them.
- The Stake Launcher is very efficient against Vampires , dealing around 1000 damage to them. This is likely a reference to classic vampire lore, in which a stake through the heart is one of the few surefire ways to kill a vampire.
- The Vampire can be annoying to the player, as the Vampire in its Bat form is fast and able to fly through small holes. If one is close enough to you, it reverts into its normal form and attacks.
- A Spectre Staff can be used to kill the Vampire's "bat" form, as the projectiles shot by the Spectre Staff home in on enemies, though a fast shooting weapon (such as the Megashark with Chlorophyte Bullets) can also be used to take them down.
- Now occasionally hiss/snarl when in humanoid form.
- Added to the game.
