# Initiative *Source: Player's Handbook (2024) p. 369. Available in the Free Rules (2024)* Initiative determines the order of turns during combat. The combat rules in "chapter 1" explain how to roll Initiative. Sometimes a DM might have combatants use their Initiative scores instead of rolling Initiative. Your Initiative score equals 10 plus your Dexterity modifier. If you have [Advantage](advantage-xphb.md) on Initiative rolls, increase your Initiative score by 5. If you have [Disadvantage](disadvantage-xphb.md) on those rolls, decrease that score by 5.
