Vampire Knives

The  are a new weapon to be added 1.2 update.

They can be found in Crimson Chests, which themselves can be found in the Dungeon. In order to open the Crimson Chest, you need a Crimson Key which can be obtained by killing mobs in The Crimson. The drop rate for these keys is very low.

The Knives themselves are extremely powerful. They do melee damage, so the Hallowed Melee set will apply damage bonuses to it. A full Hallowed Melee set with Godly or better Vampire Knives are able to beat Plantera with no problem. A portion of the damage dealt will be returned as health to the user. Multiple knives can hit multiple enemies or hit a single large enemy multiple times.
