From Guild Wars Wiki
- Concise description
Disguise. (50 minutes.) You look like a Hellhound.
- Two emotes work, /stand and /sit; they make the head raise slightly.
- This disguise is received by using a Skeletonic, an Everlasting Skeletonic or a Mysterious Tonic (random effect).
- While in Hellhound Form, when walking backwards (using "s") your character will walk backwards while its feet move as if it moves forward, thus allowing your character to "moonwalk".
