Warden Helmet

The Warden Helmet is a helmet that can be unlocked at Zombie Slayer 8. It halves your speed, but grants more base damage for every   you have left.

Trivia

 * Because of its base weapon damage boost, a Giant's Sword is a great option to pair with this, due to it having the highest base damage out of all weapons.
 * Having a Black Cat Pet or Rancher's Boots helps increase speed a lot, due to this item's ability.
 * Its ability is maxed out at 200, but goes up to 250 with a Level 100 Black Cat.
 * inside the Catacombs, several armor stand statues feature Warden Helmets.
