Yep, the Soulstone casts Howl every single turn. It's quite amusing during storming battles when they appear inside the castle walls... and they can distract enemy units, which is handy. There's a slight downside that your own casters might spend a lot of time casting buffing spells on wolves.

One could do some strange things based on this, such as casting large-scale boosters such as Marble Warriors or Battle Fortune to help 'em out, and letting them turn into Mandragoras via Haunted Forest.
