Rules reference

Combat in Dungeons & Dragons 5th Edition

Turn flow, actions, and common combat rules. Dungeons & Dragons 5th Edition is the world's most popular tabletop roleplaying game, where players create heroic adventurers and explore fantastical worlds filled with magic, monsters, and mystery. Using a d20-based system, players roll a twenty-sided die plus modifiers to determine the outcome of attacks, skill checks, and saving throws.

Combat rules matter most when they keep scenes moving. This page focuses on decision points and the system’s core resolution loop.

Roll loop reminder

This system uses a dice pool approach in RPG Stack’s guides: build a pool from your character traits, roll, count successes, and apply consequences.

  • Build your pool from the relevant traits.
  • Roll and count successes according to the system’s thresholds.
  • Apply consequences and record changes on the sheet.
Example: Treat every roll as a decision: success advances, failure changes the situation.
Examples
Example: Declare intent, not just an action

Instead of “I attack,” state the goal: “I push them back from the door” or “I buy time for the escape.” This makes outcomes clearer.

Example: End scenes early

Once the winner is clear, wrap it. Don’t grind out the last 10% if it doesn’t change the story.

Common mistakes (smallest fix)
  • Mistake: Unclear turns and slow decisions. Fix: State intent, pick one action, resolve fast, and move on.
  • Mistake: Grinding after the outcome is obvious. Fix: End scenes early and narrate the final advantage.
