You have mastered techniques to take advantage of every drop in any enemy’s guard, gaining the following benefits:

• First, increase your Strength or Dexterity score by 1 to a maximum of 20.
• Immediately after a creature within 5 feet of you takes the Disengage Action or hits a target other than you with an attack, you can make an Opportunity Attack against that creature.
• When you hit a creature with an Opportunity Attack, the creature’s Speed becomes 0 for the rest of the turn. Provided the target is no more than one size larger than you.
