- Upon blowing the horn, the wolf's head howls and makes a faint howling sound a moon illuminates in the crescent of the horn for a brief moment, and sparkles appear around it. A ghostly wolf head appears for a brief moment above the player, and mirrors the smaller wolf in the horn in howling leaving a foggy breath along with rings from the vibration of it's howl.
- Necromancer: Life Transfer and Tainted Shackles have the same effects as when using a horn skill if entering death shroud while wielding Howler.
