D&D Stats Explained - The Six Abilities, Minus the Fog
D&D describes every character with six ability scores: Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. Each is a number (mostly 8 to 18) that converts to a modifier (mostly -1 to +4), and that modifier is what you actually add to dice rolls. That's the entire system. The fog around stats comes from two places (the score-versus-modifier double bookkeeping, and the eternally confusing Intelligence/Wisdom split), so let's burn both off.
The six, as they play at a real table
- Strength is lifting, breaking, and hitting things with heavy objects. Melee attacks, athletics, kicking doors. The barbarian's pride and the wizard's dump stat.
- Dexterity is the hobby's famous overachiever: ranged and finesse attacks, armor class, stealth, initiative, and the most common saving throw. When veterans mutter that Dex does too much, this list is why.
- Constitution is health and stubbornness: your hit points every level and the saves that keep spells running through pain. Nobody's favorite stat, everybody's 14. Put your second-best number here; every build guide agrees because it's simply true.
- Intelligence is knowing: recall, logic, investigation, arcane theory. The wizard's engine.
- Wisdom is noticing and judging: perception, insight, willpower, animal handling. The cleric's and druid's engine, and the save that failing hurts most.
- Charisma is force of personality (not beauty, whatever the memes say): persuasion, deception, intimidation, and, for sorcerers, warlocks, and bards, literal magic.
The Int/Wis line, once and for all: Intelligence knows the rare mushroom's Latin name; Wisdom notices it's growing on a corpse and suggests not eating lunch here. Sherlock runs high Int; a good bartender runs high Wis. Plenty of people run one without the other, which is where characters get fun.
Scores vs. modifiers (the part that trips everyone)
Your score (say, 16) exists mostly as bookkeeping; your modifier (+3) is what touches dice. The conversion: subtract 10, divide by 2, round down. A 10 is +0 (average person), an 18 is +4 (peak mortal), an 8 is -1 (your dump stat, beloved).
Practical translation: when the DM says "roll Perception," you roll a d20 and add your Wisdom modifier (plus proficiency if trained, a whole other article). Digital sheets do all of this math for you, which is why new players can safely treat scores as flavor and modifiers as the real numbers.
Where scores come from (the standard array, rolling, or point buy) and where they go (your class's main stat gets the best number, Con gets the second) is character creation's whole stat decision. Two rules cover it. The rest is taste.
Do stats define your character?
Mechanically they nudge; narratively they suggest, and the suggestions are optional. An 8-Charisma character isn't rude, just unpersuasive; a 6-Intelligence barbarian played earnestly is a beloved archetype; the one-sentence personality does more characterization than all six numbers combined. Stats are the physics. You're still the driver, and the class choice shapes your night far more than the array under it.
Frequently asked questions
What do the six stats in D&D do?
Strength fights heavy, Dexterity fights quick and dodges, Constitution keeps you alive, Intelligence knows things, Wisdom notices things, Charisma moves people. Each converts to a modifier you add to related d20 rolls.
What's the difference between Intelligence and Wisdom in D&D?
Intelligence is learned knowledge and logic; Wisdom is awareness and judgment. The professor versus the park ranger. Investigation reads clues with Int; Perception spots the ambush with Wis.
How do ability modifiers work?
Score minus 10, divided by 2, rounded down: a 16 gives +3, a 10 gives +0, an 8 gives -1. The modifier, not the score, is what you add to rolls, and digital sheets calculate it automatically.
What's a dump stat?
The ability you assign your worst number because your build barely uses it: the wizard's Strength, the barbarian's Intelligence. It's standard practice and a running joke, not a character flaw; play it however you like.
What are good stats for a beginner character?
Take the standard array (15, 14, 13, 12, 10, 8), put the 15 in your class's main ability and the 14 in Constitution. That's within a hair of optimal for every class and requires zero math.
