Shielding

SHIELDING
Fighting Style Feat (Prerequisite: Fighting Style Feature)
When a creature you can see attacks a target, that is not you, whom is within 5 feet of you, you can take a reaction to use your shield to attempt to defend the target from the incoming attack - disadvantage is now on the triggering attack and all other attacks against the target until the start of your next turn, as long as you remain within 5 feet of the target.
