What Are Ability Score Modifiers
So, what are ability score modifiers? Imagine your D&D character has six big numbers called ability scores Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. These scores show how strong, sneaky, tough, smart, wise, or charming you are! They usually range from 3 (super weak) to 18 (super awesome) when you start, and ability score modifiers are the little numbers that come from them like a power boost!
Here’s the trick: ability score modifiers tell you how much extra you add (or subtract) when you roll a 20-sided die (a d20) to do stuff in the game like hitting a monster or jumping a gap. A big score gives a big modifier, and a tiny score might give a negative one. They’re like your character’s cheat codes for winning or at least not tripping over a rock!
How Do Ability Score Modifiers Work
How do ability score modifiers work? It’s like a fun math game! Every ability score—like your Strength of 15—turns into a modifier using a simple rule. Here’s how:
- Take the Score: Start with your ability score—like 15.
- Subtract 10: 15 minus 10 equals 5.
- Divide by 2: 5 divided by 2 is 2.5, but you round down—so it’s 2.
- That’s the Modifier: Your ability score modifier is +2!
If the score’s low—like 6—you’d do 6 minus 10 (that’s -4), then divide by 2 (-2). So, ability score modifiers range from -5 (for a score of 1) to +10 (for a score of 30—super rare!). In D&D 5th Edition (D&D 5e), most players start with modifiers from -1 to +4—pretty cool, right? How to use ability score modifiers tip: They pop up everywhere—so let’s see where!

- Saving Throws: A dragon breathes fire—yikes! Roll a d20 and add your Dexterity ability score modifier to dodge—like +2 if your Dexterity is 14!
- Attack Rolls: Swinging a sword? Roll a d20, add your Strength ability score modifier (like +4 for a score of 18), and see if you hit!
They also help with skills—like adding your Charisma ability score modifier to a Persuasion roll to convince a guard you’re a prince! In 2025, D&D 5e rules say ability score modifiers are the heart of every roll—making them your best buddy in the game!
