Sting Like a Bee

Through either meticulous study or rigorous training, you have learned and adopted a unique combat style that greatly utilizes sudden movements and momentum created by it. You gain the following benefits:

• When you move 15 feet or more during your turn, you have advantage on the next melee attack roll you make before the end of your turn. You cannot occupy the same space more than once during or at the end of this movement to gain this benefit.
• You can try to discern the combat style of an enemy you can see, increasing your ability to pummel them . As an action or a bonus action, you can make a Investigation or Insight check(your choice) contested by the enemies Deception check. If you succeed, for one minute you can use your bonus action to make a single attack against with an unarmed strike or a melee weapon that you are wielding in one hand.
  You cannot benefit from this ability if you cannot see the enemy. You cannot use this ability more than once per minute against the same creature.
