Amulet

Amulets in Path of Exile are pieces of equipment that players can find and equip. A character may wear only one amulet at a time. Similar to other equipment, amulets come in four rarities with associated magical modifiers and affixes. Amulets cannot hold any gem sockets.

Amulet Types and Bonuses
Unlike other equipment, amulets do not provide the character with any sort of protection. Instead, each type of amulet gives a particular magical bonus to the character.
