Daily Punch 4-1-15 Face Strike for DnD 5e

I know you can grant advantage to a friend as an action, but what if you could do it as part of a strike?

Face Strike

You go for the face to not only cause pain, but to distract your foes for your friends.  Gain the following benefits:

• Increase your dexterity or strength by 1 to a maximum of 20.
• When you make an attack with a weapon, you can take a -5 to the attack roll.  If you do and the attack hits, you damage the creature as normal, but the next ally to attack the target has advantage.
