Curse of Strahd
An arcanaloth looks like a robed human with the head of a fanged jackal or war dog. Arcanaloths usually snarl and wear expressions of hatred. However, they keep themselves well groomed and dressed. Arcanaloths prefer to attack a foe with cunning magic if possible, commonly memorizing destructive spells, yet they keep a wise eye on defense and escape as well. They also use their spell-like abilities judiciously and intelligently.
