d20 - The Heart of D&D

Primary Uses: Attack rolls, ability checks, saving throws

The iconic twenty-sided die determines success or failure for most actions in D&D. Whether you're swinging a sword, picking a lock, or resisting a dragon's frightful presence, the d20 decides your fate. Rolling a natural 20 means automatic success (and critical hits in combat), while a natural 1 often spells disaster.

Tip: Use our advantage/disadvantage feature when conditions favor or hinder your character.

d12 - Maximum Damage

Primary Uses: Greataxe damage, barbarian hit dice

The twelve-sided die represents the highest single-die damage in D&D. Barbarians rely on d12s for both their hit points and their signature greataxe attacks. While used less frequently than other dice, rolling maximum damage on a d12 delivers devastating results that can turn the tide of battle.

Example: A barbarian's greataxe deals 1d12 + Strength modifier slashing damage.

d10 - Heavy Weapons

Primary Uses: Heavy crossbow, pike damage, fighter/paladin/ranger hit dice

Ten-sided dice bridge the gap between versatile weapons and the most powerful attacks. They're essential for fighters, paladins, and rangers who gain d10 hit points each level. Many two-handed weapons and crossbows use d10s for damage, making them crucial for combat-focused characters.

Also used for: Percentile rolls (2d10) to generate random numbers from 1-100.

d8 - Versatile Choice

Primary Uses: Longsword (versatile), battleaxe, cleric/rogue hit dice

Eight-sided dice appear throughout D&D mechanics. Clerics and rogues use d8s for hit points, while versatile weapons like longswords deal d8 damage when wielded two-handed. Many healing spells also use d8s, making this die essential for both offense and recovery.

Spell example: Cure Wounds restores 1d8 + spellcasting modifier hit points.

d6 - The Workhorse

Primary Uses: Shortsword, sneak attack, fireball damage

Six-sided dice are D&D's most versatile workhorses. From basic weapon damage to the iconic fireball spell (8d6), d6s appear in countless situations. Rogues add d6s for sneak attack damage, and many spells use multiple d6s to determine their effects, making this die indispensable for any character.

Multiple dice: Rolling many d6s simultaneously is where our dice roller truly shines.

d4 - Small but Crucial

Primary Uses: Dagger damage, Magic Missile, healing potions

Don't underestimate the humble four-sided die. While d4s deal the least damage, they're crucial for starting characters, backup weapons, and many spells. Magic Missile, one of D&D's most reliable spells, uses d4s for each dart. Wizards and sorcerers gain d4 hit points per level, making this die vital for spellcasters.

Magic Missile: Each dart deals 1d4 + 1 force damage automatically.

Combat Attack

Scenario: Fighter attacking with a longsword
Roll: 1d20 + Strength modifier + proficiency bonus
Example: 1d20 + 4 (18 Str) + 3 (level 5) = d20 + 7

If you have advantage (flanking, prone target), use our advantage feature to roll 2d20 and take the higher result.

Spell Damage

Scenario: Wizard casting 3rd-level Fireball
Roll: 8d6 fire damage
Save: Dexterity save for half damage (DC 8 + proficiency + Int modifier)

Our roller handles the 8d6 instantly, showing each die result and the total. Critical for fast-paced combat.

Saving Throw

Scenario: Resisting a dragon's frightful presence
Roll: 1d20 + Wisdom modifier + proficiency (if proficient)
Target: DC set by DM (typically 13-19 for dragons)

Use disadvantage if you're frightened or have other penalties affecting your mental state.
