When worn, it completely blocks one instance of damage every 5 seconds and has 16 uses. If the wearer takes damage when the shield is not active the wearer will take full damage. Nightmare Fuel can be used to repair 4 uses or 25% of its durability. It will not disappear when its durability reaches 0. Instead, it stays in the body equipment slot but has no effect until it is refueled.
- This item is highly recommended for situations where the period between hits taken is above 5 seconds, like a kiting situation.
- You can use two Bone Armors and switch between them everytime one of them is on cooldown.
- The Bone Armor was introduced in the Heart of the Ruins update.
