Dice mechanics
Dice pool basics in Dungeons & Dragons 5th Edition
Rolling multiple dice and counting successes.
Explanation
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.
At the table (quick loop)
- Pick the check: ability, skill, attack, or saving throw.
- Roll 1d20 (two with advantage/disadvantage), add your modifiers.
- Meet or beat the DC (or AC) to succeed; a natural 20 on attacks is a critical hit.
Example: Stealth check, DC 15: Dexterity +3 and proficiency +2 means you succeed on a d20 roll of 10 or higher.
Examples
Example: build the pool
Pick the two traits that match your approach (often Attribute + Skill), roll that many d10s, then count successes.
Example: raise/lower difficulty
Instead of stacking small modifiers, change the difficulty (required successes) so the decision is readable.
Common mistakes (smallest fix)
- Mistake: Rolling without a clear pool. Fix: Say the approach, then pick the two traits that define the pool.
- Mistake: Counting successes inconsistently. Fix: Keep one quick reference open (cheat sheet) during play.
