Deafened in D&D 5e — The Deafened Condition, Spells and Silence
A deafened creature can't hear and automatically fails any ability check that requires hearing. That's the whole condition in both 2014 and 2024. It doesn't affect attacks, saves or movement. Its real impact is on spells and abilities that need the target to hear you, and on perception checks that rely on sound.
Track it with the condition tracker.
