Bodyguard

You are adept at protecting your allies. You gain the following benefits:

• Other creatures provoke an opportunity attack from you when they enter your reach.
• As a Reaction to one of your allies being attacked, you can move up to 5 ft. If that ally is now within 5 ft and you are wielding a shield, you can impose Disadvantage on the attack roll. If you are not wielding a shield, you can force the attack to target you instead.
