Venom Mist is a breath attack in the Dragon Quest series. It envenomates the enemy, draining a large amount of the victim's Max HP per turn.
Venom Mist is learned by monster companions such as the fat rat. It deals 1/6th of the enemy's max HP. Oddly, in the SNES version monsters that are asleep or paralyzed cannot be envenomed as well.
Venom Mist is obtained by advancing to rank 2 of the Ranger vocation. It deals 1/8th of max HP per turn.
