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. However, it is considered overpowered, since the healing rate from this can exceed 1200 hp a minute, as well as making players immune to most damage.

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.
