Power of Friendship

You've obtained a reputation of getting things done when your friends are granting you strength. You gain the following benefits.

• If you miss with an attack roll or fail an ability check, you can gain a bonus to the roll equal to the number of allies you can see within 15 feet of you (maximum equal to your proficiency bonus).
  
• While you are the target of a concentration spell cast by an ally, you can choose to also concentrate to gain a bonus to your saving throws equal to the level of spell cast. When you fail concentration, the bonus granted by this feat disappears, but the spell does not end.
  

Once you use either feature, you may not use either until you finish a short or long rest.
