Silencer is a plain-looking dagger, a bit on the short side but otherwise apparently remarkable save that it produces no sound when it strikes something. When a creature is damaged by Silencer, they must save to avoid being affected by Silence (though the effect applies only to that creature and does not radiate out from them); if the creature is surprised by the blow (as with a sneak attack) they save at a disadvantage.

If Silencer is used to strike the killing blow against a creature, that creature cannot respond to Speak with Dead or similar affects (the creature can be contacted and even be present, but it cannot in any way respond), and if such an unfortunate is returned from the dead they will be mute, an effect that can be cured by only by Regenerate or effects of a similar power.
