Protective Reflexes

Your protective instincts and quick reflexes enable you to protect your allies when they are exposed to danger, at your own expense.

You can interpose yourself between a harmful effect and one of your allies. Whenever you succeed on a Dexterity saving throw but one of your allies does not, you may use your reaction to move up to half of your movement speed and protect one of your allies. Your ally is protected from harm if your movement would put you between the harmful effect and your ally. You then receive any of the damage directed at your ally, while your ally receives none.
