Devoted Guardian

You should choose a warded creature (player or NPC) with whom you have a deep and meaningful bond. Consult with the GM to define this bond.

You've sworn to protect a special person at all costs. Your constant vigilance and fierce dedication make you a living shield, gaining the following benefit:

• When the warded creature is the target of a melee attack and is within 5 feet of you, you can use your reaction to apply disadvantage to the attack.
• You must be conscious and not incapacitated to use this ability.
