Nazar

The Nazar is an accessory that has a 1% drop chance by a Cursed Hammer, Cursed Skull, or an Enchanted Sword (NPC). This item grants the equipped player immunity to any Curse debuffs.

Trivia
A nazar is an eye-shaped charm commonly found in the Middle East meant to ward away the Evil Eye.

The name might have come from the Indian saying "नसर न लगे" (Transliterated: "Nasara na lagē") which is said to keep that person safe from harms way.
