Rolling initiative is a tabletop role-playing game mechanic used to determine the order in which players and non-player characters (NPCs) take their turns in combat.
Rolling initiative is important because it provides a fair and consistent way to determine the order of turns, which can be especially important in games where the order of actions can have a significant impact on the outcome of combat. Rolling initiative also helps to create a sense of excitement and anticipation as players wait to see who will act next.
