Shark Tooth Necklace

The Shark Tooth Necklace is dropped by the Blood Zombie and the Drippler. It causes the player's attacks to ignore some of their target's Defense, by lowering their armor by 5. In normal mode, this can increase the effective damage of the player's attacks 2 or 3 HP, depending on the enemy's defense before this is factored in.

Tips

 * This item is very useful in pre-hardmode and early hardmode because it has a fixed armor penetration value.
 * The Shark Tooth Necklace is great for overcoming the shortcomings of early high rate, low damage weapons such as the Minishark and the Bee Gun, which fall short when fighting high defense enemies.
 * The Shark Tooth Necklace is also very effective against expert mode bosses which have heightened defense, such as Skeletron in pre-hardmode, especially since Defense is more relevant in expert mode.
