Attuning Magic Items

A magic item must be attuned to a specific ability score. To attune an item, you must perform an action that is specific to that item. 
The number of items you can attune to a given ability score is based on the value of that ability score.

• Less than 10: you cannot attune to this ability score.
• 10-14: attune 1 item to this ability score.
• 15-19: attune up to 2 items to this ability score.
• 20-24: attune up to 3 items to this ability score.
