Encourage

As a bonus action, you can utter encouraging words to your allies within 30 ft. who can hear you. Until the end of your next turn, affected allies treat any attack roll, ability check, or saving throw they make as if they did not have disadvantage. If they are not affected by disadvantage, they instead receive a bonus to the roll equal to half of your proficiency bonus (minimum 1). You can do this a number of times per long rest equal to half your proficiency bonus (minimum 1).
