Ending a Magic Items Attunement

Your attunement to an item ends when you no longer satisfy the item’s attunement prerequisites, when the item has been more than 100 feet away from you for 24 hours, and when you die. You can also voluntarily end your attunement to an item with 10 minutes of uninterrupted concentration.
