At 10th level, your skill in predicting your opponents’ moves allows you to take advantage of even the slightest opening. Whenever a creature under the effects of your Insightful Prediction feature misses with an attack roll or fails an ability check, you can use your reaction to make a weapon attack against that creature.

You can use this feature a number of times equal to your proficiency bonus, regaining all expended uses whenever you complete a long rest.
