Silent Strider Version[]
Silence (Rank 1)[]
The Garou can muffle any sound she makes, the better to creep up on an enemy or escape unnoticed. An owl-spirit teaches this Gift.
System[]
The player rolls Dexterity + Stealth. Each success adds one to others' difficulty to hear the Garou for one scene.

Ragabash Version[]
Silence (Rank 3)[]
With this, the Garou can completely silence an area around him so that no sound can be heard whatsoever, from a whisper to a bomb going off. A Snake-spirit teaches this Gift.
System[]
The player spends two Gnosis points and rolls Manipulation + Stealth (difficulty 8). Each success affects a radius area of five yards radius per success. Any Gifts which require the use of sound, such as Clap of Thunder, require the user to make a resisted Gnosis roll (difficulty 6). The winner's Gift takes precedence.
