Vow of Protection

Once per long rest, may choose one creature as the target of your vow of protection. This lasts for 24 hours and grants the following benefits:
   -If you see the target of your vow get hit by an attack roll, you may immediately use your reaction to move up to half your speed toward the attacker and make one weapon attack against it.
   -You sense the target of your vow's location as long as that creature is within 1,000 feet of you. If the creature is moving, you know the direction of its movement.
   -If the target of your vow is reduced to 0 hit points by a creature, you immediately take 2d6 psychic damage and all melee attacks you make against the offending creature are at advantage for the next hour.
