The Hellhounds of Dragon's Dogma Quest are highly similar to their counterparts in Dragon's Dogma.
The Hellhound is a large canine with dark fur and glowing red eyes. Hellhounds usually roam in small packs and are formidable enemies. A Hellhound has the ability to use Flame attacks and has a strong bite which is capable of sealing the pawns in the Arisen's party, forcing them to forgo their current turn. The creature also has the ability to cast Haste on itself and its pack. Flame-based attacks do very little damage on it. Additional Hellhounds are known to appear to aid an attacked Hellhound in battle.
The Hellhound is a Small creature, which means that aerial attacks are useless against it.
