Armor Class

Calculated as 10 + Dexterity modifier + Armor

Weapon Attack and Damage Mechanics

Melee Weapons: Attack roll = d20 + Proficiency Bonus + Strength modifier; Damage = Strength modifier
Ranged Weapons: Attack roll = d20 + Proficiency Bonus + Dexterity modifier; Damage = Dexterity modifier
Finesse Weapons: Attack roll = d20 + Proficiency Bonus + Dexterity modifier; Damage = Dexterity modifier
Thrown Weapons: Attack roll = d20 + Proficiency Bonus + Strength modifier; Damage = Strength modifier

Ability Checks and Passive Checks

Difficulty Classes: Very Easy (5), Easy (10), Medium (15), Hard (20), Very Hard (25), Nigh Impossible (30)
Passive Checks: Score = 10 + all modifiers, includes Proficiency Bonus if applicable
Group Check: At least half of skilled characters succeed to allow group success

Stealth and Hiding

Hiding involves contested Stealth checks against the Perception checks of actively searching creatures and passive perceptions of others
Lightly Obscured: Disadvantage on perception checks using sight
Heavily Obscured: Inflicted with the blinded condition

Movement and Terrain

Difficult Terrain: Costs an extra movement point
Climbing/Swimming/Crawling: Also costs an extra movement point; may require Athletic checks

Jumping Mechanics

Long Jump: Distance = Strength score with a 10-foot run-up; check to clear obstacles
High Jump: Distance = 3 + Strength score with a 10-foot run-up; check to clear obstacles

Falling and Suffocation

Falling damage: 1d6 bludgeoning per 10 feet (up to 20d6); lands prone unless damage equals 0
Suffocating: Hold breath for 1 + Constitution modifier minutes, followed by rounds equal to Constitution modifier

Visibility Conditions

Blindsight: Perceive surroundings without sight, common in certain creatures
Darkvision: See in dim light as bright and darkness as dim, colorblind in darkness
Truesight: See through magical darkness and illusions, as well as into the Ethereal Plane

Rest Mechanics

Short Rest: At least one hour; can use hit dice + Constitution modifier to regain HP
Long Rest: At least 8 hours, with 6 hours of sleep; interrupted activity can void the rest

Combat Mechanics

Surprise: Contest Stealth against opposing creature’s passive perception; surprised creatures cannot act on the first turn
Prone: Can drop prone without using speed; standing up costs half movement
Opportunity Attack: Reaction attack when a creature moves out of reach

Actions in Combat

Dash: Doubles movement for the turn
Disengage: Movement does not provoke opportunity attacks
Dodge: Attackers have disadvantage; advantage on Dexterity saving throws
Help: Grants advantage to aided creature on attack before your next turn
Ready: Delay an action until a specified trigger occurs

Attack Mechanics

Critical Hit: Roll all relevant dice for the attack twice
Damage Resistance: Takes half damage from a specific type
Damage Vulnerability: Takes double damage from a specific type

Death Mechanics

Instant Death: Remaining damage after reaching 0 HP equals or exceeds maximum HP
Death Saving Throws: Rolling a d20: 2-9 = fail; 10-19 = succeed; 1 = 2 fails; 20 = stabilizes
Stabilizing a Creature: DC 10 Medicine check; stable, unconscious creatures regain 1 HP after 1d4 hours

Spell Mechanics

Prepared Spells: Can be changed after a long rest; requires 1 min per level for each spell
Rituals: Spells with the "ritual" tag take 10 minutes longer but do not consume a spell slot
Casting in Armor: Proficiency required to cast spells while wearing armor
Concentration: Some spells require concentration; taking damage requires a Constitution saving throw

Area of Effect (AoE) Spells

Cone AoE: Width varies with distance from origin; extends in chosen direction
Cube AoE: Defined size originating from a point on the cube's face
Sphere AoE: Radius stretches outward from a central point

Weapon and Armor Proficiencies

Armor Proficiency: No proficiency leads to disadvantage on all related checks and rolls, and prevents spellcasting
Weapon Proficiency: Allows use of Proficiency Bonus on attack rolls
