Zone of Silence (5e Spell)
From D&D Wiki
|Casting time:||1 minute|
|Range:||Self (5ft radius emanation centered on you)|
When you cast this spell you create a sphere, centered on you, that has a 5 foot radius and protects against eavesdroppers.
When you cast zone of silence, you manipulate sound waves in your immediate vicinity so that those within the spell's area can converse normally, yet no one outside can hear your voices or any other noises from within, including certain spell effects that require a creature to hear them (such as suggestion).
This effect is centered on you and moves with you. Anyone who enters the zone immediately becomes subject to its effects, but those who leave are no longer affected.
Note: A successful Insight check to read lips can still reveal what's said inside a zone of silence.
At Higher Levels: When you cast this spell using a 5th level spell slot or higher, add 1 hour to the duration of the spell.
