Players are bastards and don't deserve advantage. Unless they bring yummy snacks.
Gaining Inspiration
Your DM can choose to give you inspiration for a variety
of reasons. Typically, DMs award it when you play
out your personality traits, give in to the drawbacks
presented by a flaw or bond, and otherwise portray your
character in a compelling way. Your DM will tell you
how you can earn inspiration in the game.
So, really, it should be, "DMs award it when you play out your personality traits, give in to the drawbacks presented by a flaw or bond, otherwise portray your character in a compelling way, or you present a suitable bribe. We suggest yummy snacks."
