Leading by Example [Persuasion]

Requires Following Suit Feat

After you perform an action, as a bonus action, you can select
a number of creatures equal to your Charisma modifier within
30 feet of you to attempt to inspire to follow suit. If, on their
subsequent turn, any of them perform the same action as you,
such as attacking the same enemy, or performing the same skill
check, they have advantage on any rolls involved with doing so.
