Damage Types

D&D 5e has 13 damage types. Creatures may have resistances, immunities, or vulnerabilities to specific types.

Physical Damage Types

Bludgeoning:

  • Blunt force: maces, clubs, falling
  • Many creatures resist non-magical bludgeoning

Piercing:

  • Puncture wounds: arrows, spears, bites
  • Often resisted by same creatures as bludgeoning

Slashing:

  • Cuts: swords, axes, claws
  • The third "physical" damage type

Important Note: Many resistances/immunities specify "from nonmagical attacks." Magic weapons bypass this.

Elemental Damage Types

Fire: Flames and heat. Very common damage type, but many creatures resist it.

Cold: Freezing temperatures. Fewer resistances than fire.

Lightning: Electrical damage. Relatively few resistances.

Thunder: Sonic/concussive force. Often paired with forced movement.

Acid: Corrosive damage. Can destroy objects.

Poison: Toxic damage. MOST resisted/immune damage type. Many creatures immune.

Special Damage Types

Radiant:

  • Holy/divine energy
  • Effective against undead and fiends
  • Very few creatures resist it

Necrotic:

  • Life-draining energy
  • Undead often immune
  • Can reduce max HP (some effects)

Force:

Psychic:

  • Mental damage
  • Mindless creatures often immune
  • Bypasses most physical defenses

Resistances, Immunities, and Vulnerabilities

Resistance:

  • Take half damage from that type
  • Applied after all other modifiers
  • Common: fire resistance on Tieflings

Immunity:

  • Take no damage from that type
  • Common: poison immunity on undead

Vulnerability:

  • Take double damage from that type
  • Rare in 5e
  • Example: Skeletons vulnerable to bludgeoning

Stacking:

  • Multiple resistances don't stack
  • Resistance + vulnerability = normal damage

Common Mistake
Thinking 'magical' is a damage type (it's not)

Common Mistake
Forgetting resistance halves damage AFTER modifiers
Common Mistake
Not checking monster stat blocks for resistances
