7) My opponent had no Line of Sight after the two walls were put up. He put vines into my "camp," (walled-off zone) but could not summon anything in there until the wall was shattered and the Line of Sight restored. Did we play this correctly?
The wall in question was wall of bone, which has the Passage Blocked trait as well as No Line of Sight.
If the wall is "passage blocked" how do we allow vines to penetrate the wall. I get that a vine could simply so underground and come up the other side, but that doesn't seem fair.
And if that's the case when is the Beast Master going to get a Rabid Groundhog who can dig under walls?
