Spiteful Tongue

Drawing an enemy to a challenge with a scathing insult shouted across the battlefield can be just as effective as an attack. Taking this feat grants you the following benefits:

• Choose either the Strength, Dexterity, Intelligence, Wisdom, or Charisma ability score to increase by 1, to a maximum of 20.
• Once per turn, you can attempt to goad a creature into focusing its attention on you. As a bonus action, choose a hostile creature within 30 feet of you to make a Charisma saving throw (DC 8 + your proficiency bonus + the ability modifier of the score increased by this feat) against your taunts. If it fails, the target accepts the challenge and is compelled to direct all its attacks at you until the end of your next turn, using its movement to make the attack if necessary. Until the challenge ends, attacks made by the target that are directed at any creatures or objects other than you are made at disadvantage. 
• Once the challenge has been accepted, all attacks directed at either you or the challenger by any other creature are made with disadvantage until the start of your next round.
