Anvil Strike does not do extra damage when next to created stone walls

I just had a game where an opponent used an Anvil Strike against me, and the target was adjacent to a stone wall created by Wall Of Stone, and there was no extra damage done.
It also might be worth checking to see if Large Weapon has the same problem.

 

Highlighted before. Wai, blocked terrain in the card text refers to blocked terrain in the board itself, not blocked terrain due to terrain attachments. Minor rewording should solve it.

 

Fixed next build:

Though it doesn't say anything about Wild Spark...
