Amulet of Warning

This magic amulet warns you of danger. While the amulet is on your person, you have Advantage on initiative rolls.
In addition, you and any of your companions within 30 ft of you can’t be surprised, except when incapacitated by something other than nonmagical sleep.
The amulet magically awakens you and your companions within range if any of you are sleeping naturally when combat begins.

Notes: Advantage: Initiative
