The occult necklace is a magical amulet that requires 70 Magic to wear. It is dropped by the smoke devil and its boss variant. Wearing it increases the player’s Magic damage by 10%, and is the only amulet to give such a bonus. This 10% bonus will also stack with existing boosts, such as the Staff of the dead.
A combination of the occult necklace and staff of the dead while using Ice Barrage would increase a player’s max hit to 38, from an original maximum of 30. The max hit increases to 42 if using a Black mask (i) or Slayer helmet (i) on a slayer task.
Players can attach an occult ornament kit, obtained from master clue scrolls, to cosmetically enhance the necklace, creating an occult necklace (or). This only alters its appearance, and gives no stat enhancements. It can be dismantled, returning the necklace and ornament kit.
