They can be found in Crimson Chests, which can be found in the Dungeon. In order to open the chest, you will need a Crimson Key which can be obtained by using a crimson key mold, a jungle temple key, and 5 of all the souls dropped by mechanical bosses. You will obtain the mold by killing monsters in The Crimson after Hard Mode has been enabled for your world. The drop rate for these key molds is 1:4000. Vampire Knives cannot have a prefix that increases their size, and because of that the best prefix is Godly. However, the knives do not go forever, when standing still, the knives will spin and fade just outside the screen.
A portion (~7%) of the damage dealt will be returned as health to the user. The knives can hit multiple enemies or hit a single large enemy multiple times. You will throw 4-8 vampire knives at a time. For example:
- One of the Knives hit your enemy and deals 90 damage, but 7% of this damage (i.e., 6) is returned to you as HP. This permits effective invincibility, due to constant healing — as long as you continue to throw the Knives. They are capable of healing almost all damage inflicted to you fairly quickly.
- Due to their healing effect, the Vampire Knives are an extremely effective weapon against Bosses.
- Ineffective against players (PvP)
The knives have a huge, and seemingly random spread, making aiming them all very difficult. Despite this, it's fairly easy to survive most encounters and out-heal any damage you may receive. Especially from bosses, where the lifestealing properties of this weapon can be seen in full effect.
However, continued use of the knives can be extremely disorienting with all that's going onscreen. It can be difficult to discern where enemy projectiles or ranged attacks may be, and you could die from not being able to see your avatar among the knife storm and healing beams while they are dealing damage.
- The knives can be thrown through walls that are only a block thick as long as the player is pushing against the wall.
- The Vampire Knives do not have a size; thus, the best possible prefix is "Godly".
- The knives will fly straight for a given time, and then start to spin in the air (still moving forward).
- Coupled with the Fire Gauntlet this weapon can do even more damage.
- This weapon is likely a reference to Dio Brando from JoJo's Bizzare Adventure; a time-stopping vampire who throws knives in an identical fashion. Specifically, this is much like Shadow Dio's knife throw from the arcade fighter of the same name, whose knives fan out in a manner similar to this weapon.
- The Vampire Knives may alternately be a reference to Sakuya Izayoi from the popular Japanese series of games Touhou Project, first appearing in the 6th game, The Embodiment of Scarlet Devil. Sakuya serves a vampire, Remilia Scarlet, and is capable of throwing torrents of knives due to her ability to stop time. Many fans also believe that Sakuya herself is a reference to Dio Brando.
- Slightly nerfed damage, use time, life steal, and knockback.
- Added to the game.
