Dutiful Guardian

You put yourself into harm’s way to protect your allies. You gain the following benefits:
• Increase your Constitution score by 1 to a maximum of 20.
• When a creature you can see within 15 feet is targeted by an attack, or a spell that requires an attack roll, you may use your reaction to leap in front of your ally and intercept the attack. The attacker has a +5 bonus to hit against you with this attack.
• When you are hit by an attack that you protected an ally from, you may reduce the damage you take by an amount equal to double your proficiency bonus.
