D&D 5e Dice Uses

d20 - The Core Die

Used for all D&D 5e ability checks, attack rolls, and saving throws. The foundation of the d20 system that powers Dungeons & Dragons.

d4 - Magic Missile & Healing

Common for low-level spell damage like Magic Missile, healing potions, and light weapon damage across different D&D campaign settings.

d6 - Versatile Damage

Shortswords, shortbows, and many D&D spells use d6s. Roll 2d6 for a greatsword or 8d6 for a fireball. Also hit dice for rogues and sorcerers.

d8 - Medium Weapons

Longswords, battleaxes, and crossbows in D&D use d8 damage. Also hit dice for clerics, druids, and other classes.

d10 - Heavy Damage

Heavy crossbows, glaives, and higher-tier weapons use d10s. Also used for fighter and ranger hit dice in D&D 5e.

d12 - Barbarian's Domain

Primarily used for greataxe damage (1d12) and barbarian hit dice. The largest single damage die in D&D 5e.

d100 - Percentile Rolls

Used for percentage-based checks, wild magic surges, and treasure tables. Common at the table for random encounters and loot generation.

Common D&D 5e Rolls

Quick reference for rolls that come up often at the table. Each assumes standard D&D 5e rules.

Attack Roll

1d20 + ability modifier + proficiency bonus. Compare the total to the target's Armor Class. A natural 20 always hits.

Ability Check

1d20 + ability modifier (+ proficiency if proficient). Used for skill checks, initiative, and contested rolls.

Saving Throw

1d20 + ability modifier + proficiency (if proficient). Resists spells, traps, and environmental hazards.

Damage Roll

Varies by weapon or spell. A longsword deals 1d8, a greatsword 2d6, and a sneak attack adds extra d6s based on rogue level.

Healing

Cure Wounds heals 1d8 + spellcasting modifier. A basic healing potion restores 2d4+2 hit points.

Death Saving Throw

1d20 with no modifiers. Roll 10 or higher to succeed. Three successes stabilize, three failures mean death. A natural 20 restores 1 HP.
