Helpful

You have become an expert at helping others, granting you the following benefits: 

•  Increase your Charisma score by 1, to a maximum of 20.
• When you take the Help action, you can aid a number of creatures equal to your Charisma modifier instead of just a single creature.
• When you take the Help action to aid another creature’s ability check, you can make a DC 15 ability check with the same ability as the creature you are aiding. On a success, that creature’s check gains a bonus equal to your proficiency bonus. To receive this bonus, the creature must be able to understand what you’re saying.
