Silence
Nothing spoken or struck inside the zone makes a sound
Silence creates an immobile zone around a point within Close range. Its radius can be any size chosen by the caster, up to 5 ft per caster level, following the same spatial progression as the Drow racial version of Darkness. No sound is created inside it, enters it, or leaves it. Creatures inside cannot hear, speak to one another, or provide verbal spell components. Psychic powers that require neither speech nor gesture remain usable.
The spell suppresses ordinary sound completely. A magical sonic effect such as Sound Assault must overcome the Silence spell in an opposed caster level check; on a failure, the portion of that effect crossing the silent zone is negated.
Dispel Magic ends the zone. Moving away from it or forcing its caster to stop maintaining any separate effect does not dispel it: the chosen point remains silent for the full duration.
