Vampire Knives

The Vampire Knives can be found in Crimson Chests in the Dungeon. It will fire between 4 and 8 knives. Inflicting damage will heal you for equal to 1/10 of the damage dealt, so dealing 100 damage will heal you for 10 Life Points. It is also great for dealing with bosses due to its life stealing capabilities.

Tips

 * Godly is the best prefix you can get with this item. It does not gain size or speed modifying prefixes.
 * This weapon essentially makes you invincible in any combat situation, even against all of the Hard Mode bosses, and deals extreme damage to boot. It's easily all-around the best weapon available in the 1.2 update.
 * Another useful life-stealing alternative is a full set of Spectre Armor used in tandem with the Magnet Sphere spellbook. This technique is particularly useful for dealing with bosses and large crowds of enemies.
 * Because of the weapon's life-stealing capabilities, it is possible to solo any boss with 400 health without ever going beneath 300, so long as this weapon is used. It is also possible to kill a boss without dying without having any armor or accessories equipped.
