The creature cannot hear. It is cut off from sound entirely, affecting its awareness, reflexes, and ability to cast spells with spoken words.

Effects

  • –4 penalty on initiative checks — cannot hear the start of a fight or react to audible cues.
  • Automatically fails Perception checks based on hearing.
  • –4 penalty on opposed Perception checks (even non-hearing ones, representing general awareness loss).
  • 20% chance of spell failure when casting any spell with a verbal (V) component — the caster cannot modulate their voice correctly without being able to hear themselves.
  • Cannot hear speech, whispered commands, or auditory signals (horns, bells, shouted warnings).
Spell failure vs. silent spell. The 20% chance applies to spells with a verbal component cast by the deafened creature. The Silent Spell metamagic feat removes verbal components entirely, bypassing this failure chance — but increases the spell's effective level by 1.

Ending the Condition

  • Magical deafness (e.g., from blindness/deafness) is removed by remove blindness/deafness or dispel magic.
  • Temporary deafness from a duration-based effect ends when the duration expires.
  • Heal and greater restoration remove ongoing deafness.

Related Conditions

  • Blinded — the sight equivalent; often paired with deafened by the blindness/deafness spell.

Common Sources

The blindness/deafness spell; shout and greater shout on a failed save; sound burst; certain sonic monster attacks; the Deafening Critical feat; proximity to extremely loud magical effects. Deafness is not a mind-affecting condition — creatures immune to mind-affecting magic are not automatically immune to deafness.
