Rolling dice online in Dungeons & Dragons 5th Edition
Use a system-accurate roller so results match the game’s mechanics. Use the links below to apply the workflow in Dungeons & Dragons 5th Edition and keep it consistent across sessions.
Workflow (do this first)
- Pick the roller that matches the system, pool, percentile, exploding d6, 2d12 Hope/Fear, etc.
- Set difficulty / DV / target before pressing roll, not after.
- Apply modifiers inside the roll, not as re-rolls or after-the-fact tweaks.
- Save the roll to history so the table can audit crits and botches later.
D&D 5e resolves rolls with a d20: roll 1d20, add your ability modifier and proficiency bonus if it applies, and meet or beat a Difficulty Class (or the target's Armor Class for attacks). Advantage and disadvantage have you roll two d20s and keep the better or worse.
Key facts
- 12 classes: Barbarian, Bard, Cleric, Druid, Fighter, Monk, Paladin, Ranger, Rogue, Sorcerer, Warlock, Wizard
- 9 races (SRD): Human, Elf, Dwarf, Halfling, Dragonborn, Gnome, Half-Elf, Half-Orc, Tiefling
- 6 ability scores: Strength, Dexterity, Constitution, Intelligence, Wisdom, Charisma
- d20 system: Roll d20 + modifier vs. Difficulty Class (DC) or Armor Class (AC)
- Proficiency bonus: Scales from +2 to +6 across levels 1-20
- Advantage/disadvantage: Roll 2d20 and take higher or lower instead of flat modifiers
Common mistakes
- Mistake: Using a generic 1d20 roller for a pool or percentile system. Fix: Pick the system-specific roller, pools, hunger, sanity loss, and crits all key off it.
- Mistake: Re-rolling until you like the result. Fix: One roll per intent; if you want another attempt, change position, resources, or stakes first.
