Normally, the wolves are summoned in a line 200 range in front of Lycan. This works fine if there is no cliff or stairs in front of him.

However, if there are cliffs or stairs, they are spawned very close to Lycan. If you now choose the +2 wolves talent, you can get stuck within them.

There should always be a small buffer range between Lycan and his wolves when summoned, to prevent this.
