Back-To-Back

Nothing can keep you pinned when you've got someone watching your back.

• On your turn, you can use half your movement to swap places with a willing party member within 5 feet of you without either of you provoking attacks of opportunity.
• When a party member within 5 feet of you is hit by an attack, you can use your reaction to swap places with them and take the damage instead.
• You can use either (not each) of these abilities a number of times equal to your dex modifier and you regain all uses after finishing a long rest.
