- Dropped by Griggs of Vinheim.
- Found on a corpse in Sen's Fortress. In the room with stairs after the first fog gate, jump down to a platform made of planks and go through the doorway to find a corpse containing Hush and the Black Sorcerer Set.
Hush silences all noise the caster makes, making both other players and enemies unable to hear them. Blind enemies will be completely unable to detect the player until they're touched. This is useful for sneaking up on enemies to backstab them, or sneak past them altogether. The short duration means that each cast is likely only useful for a single engagement.
