Feint

You have developed the technique necessary to fake out opponents when attacking. You gain the following benefits:

• PREREQUISITE: You must have proficiency in Martial weapons
• As a Bonus Action before your primary Action, you may attempt to feint the enemy. You roll a Deception (CHA) check, vs the targets passive Insight (WIS)
  On a success, you gain advantage on your next melee attack against that target this turn.
  On a fail, the target gains an opportunity attack against you, it is optional for them and would use their reaction to strike at you. You still attack as normal after their opportunity.
