Cheat Sheet

How hard is it? (DC)

Advantage and disadvantage

• Advantage: roll two d20s, keep the higher.
• Disadvantage: roll two d20s, keep the lower.
• Both at once? They cancel. Roll one die.
• Natural 20 on an attack: always hits, critical hit (roll damage dice twice). Natural 1: always misses.

The three kinds of rolls

• Ability check: trying something hard. Target: the DC.
• Saving throw: resisting danger. Target: the DC.
• Attack roll: hitting a foe. Target: their Armor Class (AC).

Your turn in a fight

• Move up to your speed (usually 30 ft = 6 squares).
• One action: Attack, Magic, Dash, Disengage, Dodge, Help, Hide, Ready, Search, Study, Influence or Utilize.
• Free: draw a weapon or open a door, and say a few words.
• Bonus action only if a feature or spell gives you one.
• One reaction per round, such as an opportunity attack.

Making an attack

1. Roll d20 + attack bonus.
2. Meet or beat the target's AC to hit.
3. Roll damage + your modifier.

Cover: low wall +2 AC, arrow slit +5 AC.

At 0 hit points

• You fall unconscious. Each turn, roll a d20 (no modifiers).
• 10+ success, 9 or less failure.
• 3 successes: stable. 3 failures: you die.
• Natural 1 = two failures. Natural 20 = wake up with 1 HP.
• Any healing wakes you up.

Resting

• Short rest (1 hour): spend Hit Point Dice to heal.
• Long rest (8 hours): back to full HP, all spell slots back.
